WebA dot plot of forward light scatter versus 90 o side scatter is a measure of cell size and cell granularity respectively, the latter being dependent upon the presence of intracellular structures that change the refractive index of light. Cell condensation during early apoptosis is seen as a decrease in forward light scatter only. As apoptosis proceeds, both forward … WebFL, fluorescence; PMT, photomultiplier tube; SSC, side scatter; FSC, forward scatter; blue arrow, light path. Optics and Detection. Fluorescence measurements taken at different wavelengths can provide quantitative and qualitative data about fluorophore-labeled cell surface receptors or intracellular molecules such as DNA and cytokines.
