Flow cytometry light scatter
WebOct 25, 2024 · The scatter parameters can be used to identify small debris in the culture, as well as larger aggregations of cells. As flow cytometry is a single-cell technique, getting rid of these aggregates is an important step … WebAbstract. Flow cytometry is a powerful tool for interrogating the phenotype and characteristics of cells. It is based upon the light-scattering properties of the cells being analyzed and these include fluorescence emissions. This fluorescence may be associated with dyes or conjugated to mAbs specific for molecules either on the surface or in ...
