To analyze cell sub populations, you create gates and apply those gates using one of many methods. In FCS Express, plots and statistics update immediately in real time as you move gates, markers, or quadrants, allowing you to evaluate your gate placement on the go.
FCS Express supports five types of drawing gates, and another type, called combination gates, which can combine any number of other gates in several ways. You can create an unlimited numbers of gates or create a gate matrix. You can also create gates directly on images with FCS Express Image Cytometry.
