[Immunological and enzymatical activity after dimiimidoester fixation (author's transl)].

The paper is concerned with the capability of diimidoesteras as histochemical fixatives. findings of diimidoester-fixed human erythrocytes show the receptor activity these cells had retained. Due to these properties amidinated red cells proved well suited as storable immunosorbens for ensuing tests of haemagglutination. Following immunisation with horseradish peroxidase of rats, diimidoester-fixed plasma cells were highly reactive towards HRP in contrast to only moderately stained glutaraldehyde fixed cells.
