How to prepare my sample?
Sample needs to be in a single cell suspension. Preferably in PBS or low seerum. The ideal concentration, which would work for all cell types, is impossible to define. The starting point could be 1-10 million cells / ml. Usually, the easiest way is to start with too high concentration and then dilute the suspension when needed (in this case, don’t forget to bring appropriate buffer with you).
Always filter samples before sort and remember to have buffer for the sort collection.
