[Influence of embedding media on the fading of FITC-labelled coverslip cultures [author's transl)].

The influence of embedding media on the fading of FITC-labelled coverslip cultures was tested. It was found, that the value of the fading depend on the pH value of the embedding media. In glycerin-PBS pH 8.5 as embedding media and immediate measuring the fluorescence intensity, the decrease of the fluorescence intensity after 300 seconds blue light excitation was 5%.
