Assay Conditions

Abstract We describe a method for determining serum alkaline phosphatase activity with use of N-methyl-D-glucamine buffer, Na+ is a definite activator, whereas NH4+ and Li+ inhibit enzyme activity. Optimum reaction conditions are: methylglucamine buffer, 0.35 mol/L, pH 10.2 +/- 0.1 (30 degrees C); NaCl, 70 mmol/L; MgCl2, 0.5 mmol/L; disodium 4-nitrophenyl phosphate, 15 mmol/L; reaction temperature, 30 degrees C; reaction time, 2 min. The assay conditions are optimum for all human serum isoenzymes.

Prepubertal Girls

Abstract We determined plasma (serum alkaline phosphatase activity in 854 healthy students of the Rochester, Minnesota, public schools. Prepubertal girls had somewhat greater upper limits than did boys, and there was a low trend of increasing activity in both sexes. At the beginning of adolescence increasing activities were observed, which peaked at ages 11 to 12 years in girls and at ages 13 to 14 in boys. Adult values were not reached until six to eight years later. In 180 pairs of siblings, a significant intraclass correlation was noted. A possible role of alkaline phosphatase in the regulation of protein synthesis is suggested.
