摘要

1352293 Kallikrein-trypsin inhibitor BAYER AG 30 March 1972 [3 April 1971] 15028/72 Heading C3H A process for the separation of kallikreintrypsin inhibitor from an aqueous mixture comprises adsorbing the said kallikrein-trypsin inhibitor on a non-ionic, porous, cross-linked copolymer of styrene and divinylbenzene having an active surface area of 10-1000 mSP2/SP/g., separating the remainder of the mixture from the resin and eluting the inhibitor from the resin. Preferably the absorbed material, which is generally obtained from animal organs, is washed with dil.HCl, and a dilute aqueous solution of sodium E.D.T.A.
