[Immunochemical characteristics of the peroxidases of several mouse tissues]
Enzymes catalyzing peroxidase reaction of a lysosomal fraction in bone marrow, leucocytes, spleen, thyroid gland, stomach, kidney, heart, lungs, brain and skeletal muscle of mice were investigated by immunochemical methods. A high level of peroxidase activity was discovered in leucocytes, bone marrow, spleen, heart and lung, a lower activity appeared to be characteristic of liver, thyroid gland and kidney. The peroxidase activities in brain, skeletal muscle and stomach were low. The reaction of immunoprecipitation with myeloperoxidase-specific antiserum revealed considerable antigenic distinctions between the enzymes catalysing peroxidase reaction in various tissues of mice.
