An approach to the isolation and physicochemical study of the chains of IgM is presented. The chains were separated after mild reduction in the absence of guanidine as the maleylated derivatives. The maleylated μ and κ chains were isolated in pure

The soluble antigens of Clostridium perfringens type D have been separated into four fractions by chromatography on DEAE-cellulose. The fractions were examined for their biological activity and for their homogeneity by starch gel electrophoresis, dou
