Abstract

PURPOSE:To purify the titled substance simply in high yield, by treating a solution of raw kallikrein with an insoluble type kallikrein antibody, adsorbing it on the antibody, washing the antibody, eluting kallikrein with an alkali aqueous solution. CONSTITUTION:An antibody obtained by immunizing an animal against kallikrein having the desired purity is chemically linked to an insoluble type carrier such as agarose, dextran, etc. by covalent bond, to prepare an insoluble type kallikrein antibody. A solution of raw kallikrein obtained from a well-known kallikrein-containing raw material such as urine, blood, etc. of an animal by a well-known method is treated with the insoluble type kallikrein antibody, so that kallikrein is specifically adsorbed on it. The antibody is washed to remove impurities, and kallikrein is eluted with an alkali aqueous solution such as 0.2M aqueous solution of Na2CO3, etc. Thus, high-purity kallikrein can be obtained in high yield.

Conventional methods for purifying kallikrein include ammonium sulfate salting out, solvent precipitation, ion exchange chromatography using cation and anion exchangers, electrophoresis, and affinity chromatography using inhibitors. These methods have the disadvantages that it is difficult to separate and remove kallikrein and hybrid proteins, lack % isomerism, and require considerable time and effort.
