-
This assay is based on a kinetic reaction. Use of a multi-channel pipettor is recommended. Addition of Working Reagent to samples should be quick and mixing should be brief but thorough. Assays can be executed at room temperature or 37°C.
Procedure using 96-well plate:
1. Transfer 200 µL distilled water (H2O) and 200 µL Calibrator into separate wells of a clear bottom 96-well plate.
2. Carefully transfer 5 to 50 µL samples into other wells.
3. Pipet 150 to 195 µL Working Solution to sample wells. The final reaction volume in the sample wells should be 200 µL. Tap plate briefly to mix.
4. Read OD405nm (t = 0), and again after 4 min (t = 4 min) on a plate reader.
Procedure using Cuvette:
1. Transfer 50 µL samples into 1-cm cuvettes.
2. Pipet 950 µL Working Solution to samples. Mix briefly.
3. Read OD405nm shortly after the mixing, and again after 4 min. - 试剂准备
-
Equilibrate reagents to room temperature. The Working Solution is prepared by mixing for each 96-well assay, 200 µL Assay Buffer, 5 µL Mg Acetate (final 5 mM) and 2 µL pNPP liquid substrate (10 mM). Fresh reconstitution is recommended, although the Working Solution is stable for at least one day at room temperature.
- 样品制备
-
ALP is stable for 48 hours at 4°C and 2 months at - 20°C. EDTA, oxalate, fluoride, citrate are known inhibitors of ALP and should be avoided in sample preparation. Serum, plasma (no EDTA/citrate, ideally unhemolyzed) and cell culture media can be assayed directly. To measure intracellular ALP, cell lysate can be prepared : 10 4 cells are washed with PBS and lysed in 0.5 mL 0.2% Triton X-100 in distilled water by shaking for 20 min at room temperature.

Quantitative determination of alkaline phosphatase ALP activity using stable p-nitrophenol phosphate substrate at 405nm.
Alkaline phosphatase (ALP) catalyzes the hydrolysis of phosphate esters in an alkaline environment, resulting in the formation of an organic radical and inorganic phosphate. In mammals, this enzyme is found mainly in the liver and bones. Marked increase in serum ALP levels, a disease known as hyperalkalinephosphatasemia, has been associated with malignant biliary obstruction, primary biliary cirrhosis, primary sclerosing cholangitis, hepatic lymphoma and sarcoidosis. Simple, direct and automation-ready procedures for measuring ALP activity in serum are becoming popular in Research and Drug Discovery. The Alkaline Phosphatase Assay Kit is designed to measure ALP activity directly in biological samples without pretreatment. The improved method utilizes p-nitrophenyl phosphate that is hydrolyzed by ALP into a yellow colored product (maximal absorbance at 405nm). The rate of the reaction is directly proportional to the enzyme activity. p-Nitrophenyl phosphate p-nitrophenol + phosphate
