Chromogenic substrates for the assay of alkaline phosphatase (EC and acid phosphatase (EC

Alkaline phosphatase is also known as:

Basic phosphatase; alkaline phosphomonoesterase; phosphomonoesterase; glycerophosphatase; alkaline phosphohydrolase; alkaline phenyl phosphatase; orthophosphoric-monoester phosphohydrolase (alkaline optimum); ALP; ALKP; ALPase; Alk Phos.

Acid phosphatase is also known as:

Acid phosphomonoesterase; phosphomonoesterase; glycerophosphatase; acid monophosphatase; acid phosphohydrolase; acid phosphomonoester hydrolase; uteroferrin; acid nucleoside diphosphate phosphatase; orthophosphoric-monoester phosphohydrolase (acid optimum); AP; ACP.


Phosphatases are hydrolase enzymes which remove phosphate group from other molecules. Measurement of phosphatase activity can be performed to detect phosphatase-active bacteria. In humans, elevated serum alkaline phosphatase levels have been associated with various diseases, such as biliary obstruction, bone conditions, liver diseases and leukemia.
