A flow cytometer collects the events you are interested in, and also ‘sees’ every event that goes through. This includes debris and even bits in your buffers. As cytometrists, we gate our cells to exclude unwanted bits and to focus on the sub-populations that we are interested in studying. There are two main ways of gating…
If, like many people, you use fluorescent proteins to view your transfection efficiency or your CRISPR gene editing, you can also isolate cells with different expression levels of fluorescent proteins. Here are 5 ways to improve your sorting experiment.
Your reagents should do ‘Exactly what they say on the tin.’ This only happens though if you look after them in the way the manufacturer states on their data sheets. We have all been guilty of using reagents past their expiration date. Usually we can get away with it, but there are a few things…
No, this is not a call for Geeks to take over the world – just a tiny part of it – the part that ensures success in all experiments or at least a good way to analyze them if they fail. There are all too many entry points for error and variability that can be…
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),…
Over the past few decades the mammalian cell cycle has been well documented. Although there are lots of checkpoints as cells move through the cycle, we can very simply divide the cell cycle into three stages according to the DNA content in the nucleus. When cells are either quiescent or not dividing they have the…
