The enzyme alkaline phosphatase (ALP, alkaline phenyl phosphatase, also abbreviated PhoA) is a phosphatase with the physiological role of dephosphorylating compounds. The enzyme is found across a multitude of organisms, prokaryotes and eukaryotes alike, with the same general function, but in different structural forms suitable to the environment they function in. Alkaline phosphatase is found ...
In the initially published VCC experiments [1] only the internal 60 wells of the plate were used, since evaporation changed the volume of the edge wells during the 12-hour incubation. However, all 96 wells of the 96-well plate can be used for the experiment as long as the edge of the plate is wrapped with a piece of Parafilm M six squares long ...
ALP activity is significantly increased in the third trimester of pregnancy. [11] This is due to increased synthesis from the placenta as well as increased synthesis in the liver induced by large amounts of estrogens. [11] [12] [13] Levels in the third trimester can be as much as 2-fold greater than in non-pregnant women. [11]
In microbiology, a colony-forming unit (CFU, cfu or Cfu) is a unit which estimates the number of microbial cells (bacteria, fungi, viruses etc.) in a sample that are viable, able to multiply via binary fission under the controlled conditions.
Elevated alkaline phosphatase occurs when levels of alkaline phosphatase (ALP) exceed the reference range. This group of enzymes has a low substrate specificity and catalyzes the hydrolysis of phosphate esters in a basic environment. The major function of alkaline phosphatase is transporting chemicals across cell membranes. [1]
Specific activity gives a measurement of enzyme purity in the mixture. It is the micro moles of product formed by an enzyme in a given amount of time (minutes) under given conditions per milligram of total proteins. Specific activity is equal to the rate of reaction multiplied by the volume of reaction divided by the mass of total protein.
However, when experiments have been carried out in-vivo, phosphatase enzymes have been shown to be incredibly specific. [3] In some cases, a protein phosphatase (i.e. one defined by its recognition of protein substrates) can catalyze the dephosphorylation of nonprotein substrates. [ 4 ]
