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.
