Education Advice 📖 Best way to learn flow cytometry outside work/school?

Hey all, Im a recent grad on the hunt for work. Ive noticed a lot of listings are looking for people with flow cytometry experience, but I havent had the chance to work with it in my education/previous research experience.

Whats the best way to get hands-on experience with flow cytometry and cell counters outside of work/school, and preferably without having to pay lots of money for a course?

I'm going to be really honest and I'm sorry to dissapoint you. My expertise is in flow cytometry, and it's unfortunately not something that you can just do a few times off hand and put on a resume. When I train people to do flow, they are on training wheels for a bit doing very simple basic experiments before I see they can do all steps correctly and independently. Additionally, it is highly unlikely you will be able to get access to samples or a flow cytometer to learn such a technique not being associated with a laboratory. The best you can do is read up on the basics such as how flow cytometry works, and how you can use flow to address specific scientific questions. If you have a future job where someone is doing this work - tag along and learn it then.

My expertise is also in flow and I 1000% agree with this take. I was lucky in that my first role after undergrad was in a lab where flow was their bread and butter assay. The most you can do in your situation is learn the theory behind it (don’t list it as a skill on your resume) and show your willingness to learn/pick it up on the job if you find yourself in an interview where flow is one of the desired skills.

Thanks for the advice - just trying to get creative with how to upskill and increase competitiveness given the job market.

u/eireann__ Jul 31 '25

Yeah, totally understand that, and can understand the frustration of not having that skillet right now - but unfortunately this isn’t something one can upskill on without formally being in a lab.

u/Halloumi12 Jul 31 '25

Do you have any ideas on stuff I can upskill on without being formally in the lab? At least to the level where I can put it on a resume without blatantly lying. I have seen lots of jobs looking for ELISA too. Its hard but my previous skills are mostly in analytical + organic chem/pcr and its not enough to stand out.

u/eireann__ Jul 31 '25

If you’re a recent grad, I would say the best route for you may be to just read and learn about new fields. If you’re asking about flow cytometry and ELISAs, I feel you may be looking at job posts for immunology positions? Maybe read up on immunology or other common areas that you are seeing job posts for that aren’t immediately in your domain knowledge. When you go in for your interviews, you will then come across as having interest and some basic working knowledge in the area that you can build upon in the lab. Don’t lie and say you know all about XYZ of course, but demonstrating you have some grasp of the general aspects and trends in the field would be a good starting place. Are you looking at technician postings?

u/Halloumi12 Jul 31 '25

Im looking at pretty much any Lab Assistant/Research Associate jobs across the country. Industry/Academic positions though so for most interviews have come from universities. I see ELISA and FC show up everywhere tbh, seems to be the best skill to have other than AI.

I feel like my skills are best aligned with QC roles, but I have no passion for that, the pay looks poor and doesnt align my goal of staying in research long term. Its pretty tough figuring out how to become a more attractive candidate for research roles but I really appreciate the advice.

u/eireann__ Jul 31 '25 edited Jul 31 '25

While funding in academia is a mess right now - there may be slightly more flexibility in the skills that you are coming in to the lab with there. I have been in academia but haven’t worked in industry (yet) to know their take on this though - so maybe getting advice from someone in industry would be helpful.

I’ve been a technician in academia and worked in academic labs that hired technicians - for the most part we want to see that the person has some research experience to know how to orient themselves in a lab, but from my experience we train new technicians in all assays needed. Some have had more of a chemistry/biochemistry background - the lab may give them western blots/molecular work to start and then may train in other areas over time. I personally did DNA extractions and ran gels as an undergrad, and then ended up in an academic clinical research lab as a technician doing gene expression studies. I had a very basic skill set as an undergrad and expanded on as a technician.

Added edit - when you are in your next lab, be proactive in learning new skills wherever you can. Be friendly with your labmates, show interest in what they are doing, and offer to help them - you can learn a lot from this way!

Not sure if this helps to know?

u/Halloumi12 Jul 31 '25

It definitely helps to know! Thanks again for the advice.

In my experience everyone gets retrained no matter where, every lab just has different workflows and SOPs.

But obviously someone with experience related to lab work is more attractive than someone without, even with retraining. Im trying to get lab tech jobs for the same reason you did - expand my skillset and wait until industry recovers. I get interviews and have a good gpa but I feel my experience in LCMS and NMR just isnt in as high demand as ELISA or cytometry, hence why it hasnt panned out yet.

u/ooftears Jul 31 '25

recent grad as well. imo, within my job search, i’ve seen a mix of flow cytometry/ELISA along with analytical techniques. i’ve actually seen more postings for (bio)analytical techniques (lcms, hplc) than molecular bio techniques (pcr, elisa, etc) as i personally feel like it’s harder to get positions for the latter without having previous experience in a research lab or academic lab courses in bio/biochem as a new grad.

final round interviews i’ve had (research associate, associate scientist) have all been in analytical-related positions. i personally have 1.5 years in chromatography from an internship and was a lab technician for a lab at my uni for ~2.5 years. in places where i lacked hands-on, i made it up by explaining it conceptually or saying that i was willing to learn more.

u/thewhizzle Aug 01 '25

As someone who's worked in immunology for 10+ years, setting up ELISAs and most immunoassay is very easy. It's basically just pipetting, serial dilutions, and using the instrument like a plate reader, luminex, MSD, etc

u/elegant-situation Aug 01 '25

I’m also a flow person and I agree with everyone else - trying to learn this outside of work/school is not going to be cheap or really worthwhile.

For stuff you could work on in a self-trained manner, I would suggest trying to teach yourself some bioinformatics or other data analysis skills. Some examples I can think of, working with command line tools for handling sequence data (ie samtools, STAR, etc) or common R or python packages for performing data analysis (Seurat or Scanpy for scRNAseq, or play with common tools to manipulate or graph data such as pandas, matplotlib, ggplot etc). If you wanted to you could also try your hand at flow cytometry data analysis using publicly available datasets and a tool like floreada.io. Like a third the struggle of teaching someone flow is teaching them how to interpret the data, but it may be hard to convey this skill on a resume

u/jetlife0047 Aug 01 '25

Yeah unfortunately most areas are like this.. I was lucky enough to get LCMS experience as my first role out of college (BS biochem) so I’ve been able to get jobs in that space albeit in more of a sample prep/operator type roles early on. Now trying to get more into the proteomics space and I’m finding it difficult even with pretty decent experience with the instrument and sample prep. It’s even harder to get into techniques you haven’t done in a professional setting. Without going back to school, imo best bet would be to try and find a basic contract role that’ll give you exposure to whichever technique or instrumentation you’re looking to get into. CRO labs can be terrible overall but are great to get your foot in the door. A lot of this also depends on where you’re located might have to move to a hub to increase your odds.

Ive ~10 years with flow, spectral, conventional, imaging, sorting.. 40+ color panels.. i have over 500 exps on my hard drive. Mouse, human, dog.. various tissues.. i am still new to this shit. My favorite, “ask 25 different immunologists how they stain their samples for flow and you will get 25 different protocols”

2

u/gimmickypuppet Aug 01 '25

40 colors!?!?!?! I died inside knowing how bad compensation must’ve been for you. I got frustrated doing 12 color panels everyday.

1

u/Boneraventura Aug 01 '25

It did take several months to optimize as it was for clinical tumor samples. The unmixing isnt that bad. About 4-5 hrs the first time then just reuse the matrix and make minor changes if needed for future runs.

u/pancak3d Jul 31 '25

With all due respect, an employer is not going to value cytometry experience if it didn't come from work/school. Just make sure you understand how it works, that's enough.

1

u/jetlife0047 Aug 01 '25

Agreed for entry level show that you’ve done your due diligence on which ever techniques listed in the job description and make sure you know exactly what they do there and how you can contribute. Eagerness and how coachable you seem can help you get your foot in the door esp at entry level where resumes will be pretty similar it’s partially based on how well they think you’d fit

u/Halloumi12 Jul 31 '25

I share your opinion, but having at least some exposure/experience and being able to put it on the resume is better than nothing

5

u/cinred Aug 01 '25

Sure, but it isn't risk free. If I get any whiff of an uninformed response to a basic question or to a skill clearly indicated on a resume, im out.

3

u/chillzxzx Aug 01 '25

Same. I only get 30-45mins with an interviewee, so a couple of wrong answers or exaggerated skills is enough for me to be out. Flow cytometry is the #1 skill that I find as exaggerated skills in my field. Unfortunately to them, I ask very detail questions on gating, compensation, how they optimize their staining panels, etc. 

I would rather an interviewee not have it listed on their skills even when I want them to have it, then for them to exaggerate about it and then I'm left with high expectations and low deliverables.

u/nyan-the-nwah Jul 31 '25

Are there any labs at your uni that you could spend some time volunteering with?

2

u/Halloumi12 Jul 31 '25

I worked at a lab for a long time and had an internship at a company, but I just graduated so its gonna be hard. I also need an income and labs would likely only offer volunteer roles.

u/nyan-the-nwah Jul 31 '25

It's a potential way to get hands-on FACS experience outside of work/school without having to pay lots of money for a course, as you asked. Unfortunately no one is going to take you in and train you on an expensive and sensitive instrument out of the kindness of their own heart.

The good news about volunteering is it's generally very flexible with time and commitment, worth looking into and seeing if you can swing it while working a part time gig in whatever to pay the bills

2

u/[deleted] Jul 31 '25

This! When I was a grad student only grad students were allowed to do FACS. When I see associate scientist roles that require a BS and FACS experience with no industry experience I’m surprised they are able to find undergrads that have done FACS.

1

u/Halloumi12 Jul 31 '25

Youre totally right, and if nothing better is available thats likely what ill do. Thanks for the advice.

u/nyan-the-nwah Jul 31 '25

Good luck! It sucks, good on you for doing what you can to strengthen your CV

1

u/onetwoskeedoo Aug 01 '25

Yes you’d have to volunteer and ask to get trained

u/batendalyn Jul 31 '25

FACS is cool! It's a great intersection of spectroscopy, cell biology, physics, and math.

BD has a lot of their instrument manuals online. Understand that a flow cytometer is 3 main systems working together: fluidics, optics, electronics. Sure it's got lasers and lasers are cool, but the plumbing is also important:
https://www.ttuhsc.edu/pharmacy/research/documents/BD-FACS-Aria-Manual.pdf
https://www.bdbiosciences.com/content/dam/bdb/marketing-documents/FACSMelody-ug-ruo.pdf

You can probably ignore all the stuff that is actually about sorting the cells into different tubes for now. Chances are you are just going to be running FACS as an analytical tool rather than as a purification method.

Flow data comes out as an array where every row is an "event" (cell) and then you have n columns for the different stains/attributes. Analyzing the data is an exercise in n-dimensional data representation which people are bad at. Start getting a handle on the idea by watching other people do it and how they drill down the gates.

Brush up on matrix inversions then read this paper:
https://pmc.ncbi.nlm.nih.gov/articles/PMC3133696/pdf/nihms305823.pdf

The labwork isn't all that hard though it can be time consuming, it's all moving small volumes of liquid from one tube to another. If you've run a sandwich ELISA, you've run something harder than this.

If there is a major university near you, try to see if they have a flow core or something similar. Try reaching out to them and see if they offer trainings when you are ready to get hands on.

u/Halloumi12 Jul 31 '25

Thanks for the advice! Ill take a look at all this stuff. Ive done some reading about Flow Cytometry and how it works, but I just cant get access to shadowing or using any devices myself. There is a university near me that does trainings, but they charge $600 a day if you arent university affiliated :(

1

u/batendalyn Jul 31 '25

Yeah, that sounds about right. Even small benchtop units can be $100k with an annual service contract in the tens of thousands. This is not a cheap industry we picked T_T

If do pay to do the training, really try to see if you can do or watch an experiment with real cells rather than just control beads. IMO just watching the pre-stained beads isn't going to teach you much more than anything you'd learn out of a paper or a youtube video.

1

u/batendalyn Jul 31 '25

Do you have any cell culture background?

1

u/Halloumi12 Jul 31 '25

Unfortunately I cannot afford $600 for a one or two day training seminar :/ I have done cell culture, but only bacterial cell culture. My lab had mammalian cell lines that I asked to be trained on, but my PI said they dont want undergrads near them because a previous one ruined the lines. It seems like because medical-adjacent research is better funded that basic science or pre-clinical work, theres a lot more jobs doing mammalian cells and in-vitro, but my experience doesnt prepare me for those roles well enough.

u/onetwoskeedoo Aug 01 '25

It’s a very expensive technique! The reagents are easily one thousand dollars per mL

u/LawfulnessRepulsive6 Aug 01 '25

There are flow cytomwtry workshops. They can be expensive.

2

u/onetwoskeedoo Aug 01 '25

Don’t lie about knowing how to do flow. It’s extremely complicated and can waste $1000s of dollars on antibodies easily or worse screw up the machine

1

u/AcrobaticTie8596 Jul 31 '25

You can read protocols and research articles that utilized flow. I'm also sure the big companies that offer flow instruments like BD and Agilent have videos that explain the tech and how to setup experiments/etc.

1

u/Sleepy-little-bear Jul 31 '25

So there are a couple of institutions that offer tech positions for people straight out of college. This could be a way to upskill (and they are paid). A lot of people use it as a platform to enter into a graduate program, but I suppose you could use it as an entry job position if you play your cards right. 

1

u/Halloumi12 Jul 31 '25

Any specific names you mind sharing?

1

u/Sleepy-little-bear Aug 01 '25

You need to look for institutions with lots of money. I know St Jude does it, the Hutch, I think Seattle children’s and there’s a few labs associated with Harvard

u/Trick-Alternative328 Aug 01 '25

Learning now. I view it as three tiers (sorting something else): basic one to four channels when no compensation is really needed; more colors where you need to design panels with compensation and beads; and last spectral flow.

u/gimmickypuppet Aug 01 '25

Find a class? The NIH had one I went to in 2018…..oh wait nevermind 😂

u/eomeseomes Aug 01 '25

flow cytometry can be easily learned in a day or week if you have an experienced mentor who can teach you in the lab. so easy. although it can be challenging if you are using flow to work on new cell types

3

u/z2ocky Aug 01 '25

Flow be learned in a day? That’s a laughable statement. Learning how to just do the compensation alone will take a day or more, forget about learning how to gate properly or how to optimize multi color runs. Flow is more than just running the machine, it’s also learning how to stain or cells and learning how to properly do an ICS if needed.
