ChUG #8 - Dealing with autofluorescence in spectral flow cytometry


We host Monica Delay, US Manager for Technical Application Support at Cytek Biosciences, for a discussion on autofluorescence (AF) and the tools to deal with it in Spectral Flow Cytometry. We mean to provide an introduction to this concept, and links to further your understanding. Scroll below to find a list of webinars and publications dealing with AF.
