For quantitative colorimetric determination of alkaline phosphatase (ALP) activity.
- Use only 5 μl serum or plasma sample. Linear detection range 2 to 800 U/L
- Simple 'mix-and-measure'
- Procedure allows reliable quantitation of ALP activity within five minutes
- All reagents are compatible with high-throughput liquid handling instruments
Alkaline phosphatase (ALP) catalyses the hydrolysis of phosphate esters in an alkaline environment, resulting in the formation of an organic radical and inorganic phosphate
BioAssay Systems’ QuantiChrom™ 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 hydrolysed by ALP into a yellow coloured product (maximal absorbance at 405 nm). The rate of the reaction is directly proportional to the enzyme activity.
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.
