Abstract: Teta-hemolysine was purified from Cl. perfringens strain BP6K 28 as follows: reprecipitation in the isoelectric point of the enzyme with 2 N H2SO4 containing 15% NaCl, DEAE cellulose chromatography, gel filtration on Sephadex G-100-G75 or Bio Gel P-60--P-100, rechromatography on DEAE-Sephadex A-50 and affinity chromatography. The biological activity of homogenous teta-hemolysine, estimated by complete hemolysis of human erythrocytes, exceeded 100, 000 theta E over mg protein but the enzyme was highly labile. Molecular weight of the enzyme was 53,000 daltons.
