Product Description
Alkaline Phosphatase Placental Human Recombinant, BioActive
Overview
Placental alkaline phosphatase also known as PLAP is a membranal siaglycoprotein enzyme typicallyfoundin high concentration in syncytiotrophoblasts in the placenta amid the 3th trimester of gestation. The expression of PLAP was at firstconsidered to be onlyin the term placenta, though, a human PLAP-like variant has been found,thathas more than 85% homology with PLAP itself. PLAP is expressed strictly in normal term placenta, endocervix & fallopian tube and in ovarian and proximal gastrointestinal tumors. It is also widely expressed in germ cell tumors and more recently found in seminomas.
Biological Activity
Specific activity is > 2,500unit/mg, and is defined as the amount of enzyme that hydrolyze 1.0nmole of pnitrophenyl phosphate (pNPP) per minute at pH 7.5 at 37C.
Specifications
| Purity | Greater than 95.0% as determined by SDS-PAGE. |
