title: [Distribution of acid and neutral proteases in various organs and tissues of chickens].
abstract: The radioisotopic method of 131J-labelled albumin was employed to determine the distribution of acidic proteinase activity in some organs and tissues of chickens. The highest enzymatic activities were found in intestine wall, in pancreas, and in liver. Considerably lower activities were ascertained in kidneys, brain, lungs, and heart. The different proportions of these enzymes in homogenates and supernatant fractions (106 000 g) testify to a lack of uniformity in the solubility of cathepsins in the organs tested. The tested organs, with the exception of pancreas, did not show any enzymatic activity of neutral proteinases.
