title: Study of TAMe (p-tosyl-L-arginine methyl ester) esterase activity of bovine plasma.
abstract: The TAMe (p-tosyl-L-arginine methyl ester) esterase activity of mature and immature bovine plasma was studied and compared with the activity of this enzyme in human plasma. Kaolin activation of 2 minutes was required to produce maximal activation in cattle, as compared with 1 minute activation in man. The kaolin-activated TAMe esterase values in bovine plasma were approximately one-half the values found in human plasma. The activity of this enzyme was statistically greater in immature than in mature cattle (P less than 0.05) at kaolin activation times of 1, 2, 15, and 20 minutes.
