Quantitative analysis of dyes for automated studies of cell preparations

Spectral studies were made of the dyes in solutions and also of the cytology preparations stained by these dyes. 14 dyes of the blue-violet spectral region were examined. Absorbtion and transmission coefficients of the cell nucleus and cytoplasm were measured. The data obtained allowed to elaborate a quantitative estimation of dye selection. According to this method cresyl-violet was selected as the dye for Videocon LI-421.
