Rapid method for determination of alkaline phosphatase activity in human serum with thymolphthalein monophosphate.
The solution was then cooled to room temperature and titrated using thymolphthalein as the indicator until a persistent color change was obtained.
The alkaline phosphatase present in the sample hydrolyzes the substrate thymolphthalein monophosphate, releasing thymolphthalein and inorganic phosphate.
Maternal blood placental alkaline phosphatase (PAP) activity was assayed by the Thymolphthalein Monophosphate method (4) using the maternal sera samples heated at 65[degrees]C for 7 min.
This tendency was similar at the jejunum: 632; 1151; 749 and 405 ([micro]moles thymolphthalein /min/mg protein) and ileum: 107; 225; 157 y 71 ([micro]moles thymolphthalein/min/mg protein) with the same concentrations of phytic phosphorus.
