돼지 백혈구(白血球) Iysosome의 n-butanol 추출물(抽出物)로 부터 DEAE-cellulose, Sephadex c-200 column chromatography 및 Polyacrylamide gel electrophoresis 로서 acid phosphatase, aryl sulfatase, ${eta}-glucuronidase$로서 및 cathepsin D를 분리(分離)정제하고 그 성질을 조사하였다.
DEAE-Cellulose, Sephadex column chromatography and polyacrylamide gel electrophoresis were used to purify acid phosphatase, aryl sulfatases, ${eta}-glucuronidase$ and cathepsin D in n-butyl alcohol extracts of porcine leukocyte Iysosomes. The degree of purification was quite high for all enzymes studied and some could be identified by histochemical reactions.
