Liver catalase

Abstract
Procedures for isolation of crystalline horse liver catalase, measuring catalase activity and obtaining biliverdin and biliviolin from crystalline ox and horse liver catalase were described. The molar ration of (bile pigment)/(bile pigment + heme) from liver cata-lases was given. The results of spectrophotometric analysis were discussed. The effects of ascorbic acid on the destruction of catalase by H2O2 were given.
