[Model experiments for quantitative cytophotometry using protein films (author's transl)].

Abstract

The usefulness of protein films denaturated and fixed with ethanol/ether as cytochemical model systems was investigated. Kinetics of staining with amido black 10B were analyzed as well as the spectroscopic properties of the protein-dye complex. The absorption coefficient of the complex was estimated. Data obtained so far are compared with both stained cells and the protein-dye complex in solution. Discussion focuses on the influence of fixation and the possibilities to use the films as systems for calibrating cytochemical stainings.
