A rapid and efficient method for the purification of the complement subcomponents C1r and C1s in zymogen form using fast protein chromatography

J Immunol Methods. 1988 Apr 6;108(1-2):265-9. doi: 10.1016/0022-1759(88)90428-0.

Abstract

The purification of the subcomponents C1r and C1s of the first component of complement involves multiple steps and is time-consuming. This accounts for the frequently observed partial activation of the subcomponents. In this report we propose a simplified procedure of purification using a batch method and fast protein chromatography avoiding a shift of pH. The method provides C1r and C1s in a yield of 35 and 60% respectively. In addition, this study provides a simple and sensitive test to assess functional purity of C1r and C1s with respect to the other C1 subcomponents.
