Abstract
A new procedure, consisting of affinity chromatography on DNAse sepharose, is worked out for the purification of human erythrocyte actin from an extract of acetone powder. Comparison of skeletal muscle and erythrocyte actin purified either by reversible polymerization or affinity chromatography on DNAse Sepharose led us to infer that the erythrocyte actin isolated by affinity chromatography was pure, devoid of spectrin, and was obtained in part under polymerized (di and tetrameric) forms. This partial polymerization is related to a loss of calcium bound to actin.
