Dear Sir,

Compensation is done to prevent spectral overlap and spill-over during data acquisition in fluorescence activated cell sorting (FACS). Spectral overlap occurs because the fluorophores used in flow cytometry emit photons of multiple energies and wavelengths, where emission spectra overlap, fluorescence from more than one fluorochrome may be detected in a channel [ 1, 2, 3]. With newer advanced machines with more lasers and many more detectors or “channels”, the importance of compensation cannot be undermined. The conventional single Antibody (Ab) stained cell tube run before standardization of a protocol experiment, and getting a desired compensation settings is not sufficient in this age of multicolor and multi-tube experiments, real time compensation takes care of other problems apart from compensation like steric hinderance and tube specific “spill overs”. In our experience, even if an experimental protocol is standardized beforehand with single tube run experiments, a...
