产品概述
Alkaline Phosphatase Assay Kit (Colorimetric) ab83369 is a highly sensitive, simple, direct and HTS-ready colorimetric assay designed to measure alkaline phosphatase (ALP) activity in serum and other mammalian samples.
The kit is a pNPP assay; it uses p-nitrophenyl phosphate (pNPP) as a phosphatase substrate which turns yellow (λmax= 405 nm) when dephosphorylated by ALP.
Alkaline phosphatase assay protocol summary:
- add samples and standards to wells
- add pNPP solution to sample wells (not to standards)
- add ALP enzyme solution to standard wells (not to samples)
- incubate for 60 min at room temp
- add stop solution
- analyze with microplate reader -
说明
This product is manufactured by BioVision, an Abcam company and was previously called K412 Alkaline Phosphatase Activity Colorimetric Assay Kit. K412-500 is the same size as the 500 test size of ab83369.
This kit contains 10 substrate tablets providing convenience for multiple usages.
pNPP Assays
pNPP assays are a class of phosphatase assays using p-nitrophenyl phosphate (pNPP) as a phosphatase substrate. They can be used to measure alkaline phosphatase, neutral phosphatase, and acid phosphatase activity. These different types of phosphatases are active respectively in alkaline, neutral, and acid assay buffers. pNPP assays include Alkaline Phosphatase Assay Kit ab83369 and Acid Phosphatase Assay Kit ab83367.

相关性
Alkaline phosphatase (ALP) catalyzes the hydrolysis of phosphate esters in alkaline buffer and produces an organic radical and inorganic phosphate. Changes in alkaline phosphatase level and activity are associated with various disease states in the liver and bone. -

Alesutan I et al. (2017) measured alkaline phosphatase activity in vitro in primary human aortic smooth muscle cells using ab83369. Cells were treated with phosphate (pi) or without (Ctr, and with or without additional treatment of spironolactone (Spr) or 10 µM eplerenone (Epl).

Lee YM et al. (2019) used alkaline phosphatase assay kit ab83369 to measure the serum levels of alkaline phosphatase as a marker of bone turnover. Rat groups include sham-operated (Sham), OVX-control (OVX), E2-treated OVX groups (E2), and LABE 500 mg/kg treated OVX groups (LABE) (N=10/group).
Serum ALP levels in the OVX group were significantly increased compared to those in Sham group, and oral administration of LABE (500 mg/kg) significantly reduced the serum ALP levels as an osteoporosis-related serum marker.
