The Biogenesis of Peroxisomal Catalase in Rat Liver

Rat liver peroxisomal catalase was purified to homogeneity. The starting material was purified peroxisomes, The purity of the final preparation was judged by Sephadex G-200 chromatography, SDS gel electrophoresis, spectral analysis, and immunochemical means. Two sera containing anticatalase antibodies were prepared. The first, a rabbit serum, contained a minor impurity. The anticatalase was purified forty times by affinity chromatography and the contaminating antibodies were thereby removed. The second serum, prepared in a goat, was proved to be monospecific by immunodiffusion and immunoelectrophoresis
