Acid phosphatase from psoriatic scales

Abstract

Psoriatic scales were homogenized and a differential centrifugation was performed. The 15000 × g supernatant acid p-nitrophenyl phosphate phosphatase was enriched by substrate affinity chromatography. The purification factor was calculated to 7.4. The influence of several acid radicals and metal ions was tested on the partially purified enzyme activity and… (More)
