Simplified method for purification of mouse beta 1H.
A simple three-step method was described for purification of murine beta 1H, one of the essential regulatory proteins of complement system. The method consists of heparin-Sepharose affinity chromatography; gel filtration on a Sepharose 6B column, and DNA-cellulose affinity chromatography. By this method over 10 mg of beta 1H can be purified by more than 200-fold from 100-ml of EDTA serum of various strains. Overall yield of beta 1H was about 45%. The purified beta 1H was homogeneous as judged by SDS-polyacrylamide gel electrophoresis and immunoelectrophoresis. The purified mouse beta 1H showed physicochemical properties very similar to those described for human beta 1H: mouse beta 1H is a beta-globulin consisting of a single polypeptide chain of molecular weight of 160,000. Purified mouse beta 1H retained its functional activity as the essential cofactor for the cleavage of fluid-phase human C3b by the human C3b inactivator. Immunization of rabbits with the purified mouse beta 1H resulted in the production of the potent and monospecific antibody.
