Human Alkaline Phosphatase / ALPI Protein (Fc Tag)

IAP

Catalog Number P13225-H02H
Organism Species Human
Host Human Cells
Synonyms IAP
Molecular Weight The secreted recombinant human ALPI/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 725 amino acids and has a predicted molecular mass of 79.5 kDa. The apparent molecular mass of rhALPI /Fc monomer is approximately 90-95 kDa in SDS-PAGE under reducing conditions due to glycosylation.
predicted N Val 20
SDS-PAGE
Purity > 83 % as determined by SDS-PAGE
Protein Construction A DNA sequence encoding the mature form of human ALPI (P09923) (Met 1-Asp 503),without the pro peptide, was fused with a polyhistidine tag at the C-terminus.
Bio-activity Measured by its ability to cleave a fluorogenic substrate, 4-Methylumbelliferyl phosphate (4-MUP).
The specific activity is > 10,000 pmoles/min/μg.
Research Area Cancer |Signal transduction |Phosphatase & Regulator |Phosphatase Regulator
Formulation Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
