[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.
