An Introduction to Biomarkers

During the past decade or two, the field of biomarkers has witnessed immense development. The complexity of the field mirrors its multi-faceted applications, and it is easy to get confused with the different terms used in different contexts. Hopefully, this article will help make things clearer! What is a Biomarker? The word ‘biomarker,’ has more…

2015 Staff Picks: Flow Cytometry

There’s a joke in here about our editorial team going with the flow, but I can’t quite seem to make it work (feel free to leave suggestions in the comments). Despite my inability to make a joke count, I do hope that you find these articles amusing and useful. Jen Redig, Managing Editor Spot the…

MIFlowCyt Guidelines: Helping You to Publish Your Flow Data

Wow, you’ve done it! Your experiment worked and your boss asked you to write it up for publication in your favorite journal. Where to start with presenting your flow data? Take a deep breath, help is in hand in the form of the MIFloCyt Guidelines. As with other scientific techniques, there are ‘Minimum Information about…

The Nope-Nope-Nevers of Using a Flow Cytometer

There are some wonderful toys in the lab that enable us to open up a whole new world in science. One of those is a rather pricey and an incredibly sensitive laser-based apparatus capable of counting and sorting cells, detecting biomarkers, and engineering proteins: the flow cytometer. By propelling cells through the path of the…

Troubleshooting: No Events on Your Cytometer

It’s happened to us all, you are ready to run your samples on the cytometer and you can’t see your cells on the screen. Here are a few tricks to troubleshooting this: Cytometer vs. computer connection The different types of cytometers will need different orders for switching on the cytometer and computer. Some are cytometer…

Herzenberg and the Invention of the FACS Machine

The flow cytometer that we have all grown to know and love may have only come into its own in the 1990’s, but who would have known that the first cell sorter was invented as early as the 1950’s? With the recent death of one of the key developers of fluorescence activated cell sorting (FACS),…

Setting Voltages for Optimal Sensitivity

After panel design, and titration of the reagents, the next most important step in flow cytometry is setting the proper voltages on the photomultipler tubes (PMTs). These detectors take the photons of light emitted by the fluorochromes on the cells and convert them to electrons, which ultimately become the voltage current that is digitized and…

FlowJo Software: how’s your FlowJo mojo?

Generally, once you’ve acquired your samples on a cytometer, the hard (but hopefully fun!) part of making sense of all the data begins. This can be increasingly complex depending on the number of cells, populations, parameters, and combinations. So where we use the dedicated software aligned to the analyser for acquisition, we frequently use alternative…

Basic Statistics for Flow Cytometrists – Part 1

Part of my job in running a core flow cytometry facility is to make sure that the experiments that my users run have been optimised. But that optimisation can be split up into several areas. The first area is experimental planning: What do you want to know? Can you do this by flow cytometry? And…

10 Hints For Setting Up A Core Flow Cytometry Lab

If you are establishing a flow core facility or even setting up just one cytometer, then you need to know a few things before you plan your new lab and start looking at purchasing cytometers: Before You Start 1. Know Your Customer It’s really important to know if you are going to be setting up and…

Shapiro’s Laws of Flow Cytometry

Once you have been in the field of Flow Cytometry for a bit, the name Howard Shapiro will be familiar to you. However, for those who are new to Cytometry, you might not be aware of Dr Shapiro and his fabulous book ‘Practical Flow Cytometry’. Most Cytometrists have a paper copy of this bible of Flow…
