Zusammenfassung: | biochemistry, enzymology. SUBSTANCE: invention relates to method of isolation of carboxypeptidase B from porcine pancreas and can be used in producing genetic engineering materials in biotechnology. Method of isolation of carboxypeptidase B involves extraction, precipitation with ammonium sulfate and purification and these stages are performed in buffer solutions containing 1-10 mM of L-arginine. Purification stage is carried out by chromatography method on hydroxyapatite at first and then on DEAE-Sepharose as sorbents. EFFECT: improved method of isolation, increased yield of carboxypeptidase B. 8 ex |
