[Comparison between cytochemical and gelelectrophoretic demonstration of acid phosphatases from leukocytes (author's transl)].

The cytochemical and gelelectrophoretic demonstration of acid phosphatases with substrates alpha-naphthyl phosphate and naphthol AS-BI phosphate and with couplers fast garnet GBC and hexazotized pararosanilin is described. Cytochemically best results are achieved wit naphthol AS-BI phosphate and pararosanilin, electrophoretically however with alpha-naphthyl phosphate and pararosanilin. This discrepancy ist explained by a different substrate affinity and membrane penetration of substrates.
