Top 10 Flow Cytometry Resources

I’ve been in the world of flow cytometry and cell sorting for a very long time. Now, don’t worry, this isn’t going to be some lament about the “good old days.” Well, maybe just a little. But there will be helpful takeaways, I promise.

I was trained by the incredible staff in the core facility at the University of Arizona. When I moved to UC Davis and proceeded to start up a core facility, there were very few resources to guide me. No Google communities and LinkedIn groups. Email was new, there was the Purdue Cytometry List, but that was about it. 

You certainly couldn’t get a degree in flow, and other than the annual course that alternates between Bowdoin and now Albuquerque, there were very few courses in flow. Even the publications were few. For example, I made the following simple graph of publications mentioning flow cytometry by year:

There is now more than a log increase in publications than when I started in the field. Still, when I teach, I hear questions like “How can I convince my users to set minimum baseline voltages, or use compensation controls?”

The problem remains the same. In too many labs, flow cytometry is still taught by one user training another, not based on the vast library of excellent publications. There are now a tremendous number of outstanding flow papers, and flow courses, so I’ve picked my list of favorite resources here. I’m no David Letterman, but here are my top 10 favorite flow books and articles, in no particular order.

1.Practical Flow Cytometry

Howard Shapiro

Every lab should have a copy of this book. I will be honest, Howard, if you’re reading this, I have never read it cover to cover. I have tried, but it’s so unbelievably packed with information, I can’t handle reading it chapter by chapter. Instead, I use it when I have specific questions, especially about the workings of a cytometer, and I find it fascinating. It’s humorous, it’s amazingly insightful, and it contains some of the best explanations of difficult concepts of flow in layman’s terms. It is a definite must-have. When I was a core manager, I recommended the prologue to all my users.

2. International Society for the Advancement of Cytometry Cell Sorter Biosafety Standards

Kevin L. Holmes, Benjamin Fontes, Philip Hogarth, Richard Konz, Simon Monard, Charles H. Pletcher Jr., Robert B. Wadley, Ingrid Schmid, Stephen P. Perfetto  

Everything you need to know about the biohazard issues of cell sorting.  This resource contains clear explanations on how to test your sorter, how to protect the operator, how to classify the biohazards, and more.  If you do any sorting, you must have this resource.

3. Current Protocols in Flow Cytometry

Wiley Publishing

Everything you need to know, by the people doing the work. It’s a must have for anyone doing flow and sorting. Several of the resources here are part of this work.

4. Practical Issues in High-Speed Cell Sorting

Arnold LW, Lannigan J., Current Protocols in Cytometry 1.24.1-1.24.30, January 2010

A fantastic resource for understanding sort modes, efficiency, and many other aspects of high-speed sorting.

5. Interpreting Flow Cytometry Data: A Guide for the Perplexed

Leonore A Herzenberg, James Tung, Wayne A Moore, Leonard A Herzenberg & David R Parks, Nature Immunology Volume 7, Number 7, July 2006

We’ve all been perplexed by flow data. This is an excellent resource from the Herzenberg group, who trained some of the world’s best experts. Len Herzenberg received the Kyoto prize for his work in flow cytometry in 2006. This paper is an unrivaled source for understanding the collection and presentation of flow data.

6. Modern Flow Cytometry: A Practical Approach

James W. Tung, Kartoosh Heydari, Rabin Tirouvanziam, Bita Sahaf, David R. Parks, Leonard A. Herzenberg, and Leonore A. Herzenberg

Just as the title suggests, this article is a practical walk-through of the evaluation of CD4+ T-Cells in HIV disease that explains some of the issues regarding compensation, data collection, scaling, gating, and data analysis.

7. Flow Cytometry: An Introduction

Givan, AL, Methods Mol Biol. 2011;699:1-29

Alice has a gift for explaining the technology in clear and concise terms without oversimplifying.

8. Separation Index: An Easy-to-Use Metric for Evaluation of Different Configurations on the Same Flow Cytometer

Bigos, M, Current Protocols in Cytometry (2007) 1.21.1-1.21.6

This index is often used for comparing fluorochrome brightness and determining voltage settings.  It’s used widely in our field, here’s what it means.

9. Quality Assurance for Polychromatic Flow Cytometry Using a Suite of Calibration Beads

Perfetto SP1, Ambrozak D, Nguyen R, Chattopadhyay PK, Roederer M. Nat Protoc. 2012 Dec;7(12):2067-79.

If you asked me ten years ago what I would be spending most of my time doing, this is a good explanation. Quality assurance is extremely important, often misunderstood, and not difficult to implement in your lab.

10. Standardization, Calibration, and Control in Flow Cytometry

Hoffman RA, Curr Protoc Cytom. 2005 May;Chapter 1:Unit 1.3

You might not find this on everyone’s top 10 list, but in order to get an understanding of why these concepts are so critically important, I find it useful.

So, these are a few of my favorite flow resources. What are your favorites?

My first introduction to flow cytometry was talking to a professor who’d brought one on a research cruise to study phytoplankton. It was only later that I was introduced to the marvelous world that’s been my career for over 20 years.   In that time, I’ve had the opportunity to work with researchers in many different areas, exposing me to a wide variety of cell types and more important assays. What continues to amaze me is the number of different parameters we can measure, not just the number of fluorochromes, but the information we can extract from samples – animal, vegetable…

Common Numbers-Based Questions I Get As A Flow Cytometry Core Manager And How To Answer Them

By: Tim Bushnell, PhD

Numbers are all around us.  My personal favorite is ≅1.618 aka ɸ aka ‘the golden ratio’.  It’s found throughout history, where it has influenced architects and artists. We see it in nature, in plants, and it is used in movies to frame shots. It can be approximated by the Fibonacci sequence (another math favorite of mine). However, I have not worked out how to apply this to flow cytometry.  That doesn’t mean numbers aren’t important in flow cytometry. They are central to everything we do, and in this blog, I’m going to flit around numbers-based questions that I have received…

The Fluorochrome Less Excited: How To Build A Flow Cytometry Antibody Panel

The Fluorochrome Less Excited: How To Build A Flow Cytometry Antibody Panel

By: Tim Bushnell, PhD

Fluorochrome, antibodies and detectors are important. The journey of a thousand cells starts with a good fluorescent panel. The polychromatic panel is the combination of antibodies and fluorochromes. These will be used during the experiment to answer the biological question of interest. When you only need a few targets, the creation of the panel is relatively straightforward. It’s only when you start to get into more complex panels with multiple fluorochromes that overlap in excitation and emission gets more interesting.  FLUOROCHROMES Both full spectrum and traditional fluorescent flow cytometry rely on measuring the emission of the fluorochromes that are attached…

It is no secret that I am a very big fan of the Star Trek franchise. There are many good episodes and lessons explored in the 813+ episodes, 12 movies (and counting). Don’t worry, this blog is not going to review all 813, or even 5 of them. Instead, some of the lessons I have taken away from the show that have applicability to science and flow cytometry.  “Darmok and Jalad at Tanagra.”  (ST:TNG season 5, episode 2) This is probably one of my favorite episodes, which involves Picard and an alien trying to establish a common ground and learn…

Sun Tzu was a Chinese general and philosopher. His most famous writing is ‘The Art of War’, and has been studied by generals and CEOs, to glean ideas and strategies to help their missions. I was recently rereading this work and thought to myself if any of Sun Tzu’s lessons could apply to flow cytometry.  So I have identified 5 points that I think lend themselves to thinking about flow cytometry.  “Quickness is the essence of the war.” In flow cytometry, speed is of the essence. The longer the cells are out of their natural environment, the less happy they…
