表达区间及表达系统(Source)

Human PSMA, His Tag (PSA-H52H3) is expressed from human 293 cells (HEK293). It contains AA Lys 44 - Ala 750 (Accession # Q04609-1 ).

Predicted N-terminus: His

蛋白结构(Molecular Characterization)

Online(Lys 44 - Ala 750) Q04609-1 

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 81.4 kDa. The protein migrates as 95-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

Report

 

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Monoclonal Anti-Human PSMA Antibody, Human IgG1 at 2 μg/mL (100 μL/well) can bind Human PSMA, His Tag (Cat. No. PSA-H52H3) with a linear range of 0.009-0.039 μg/mL (QC tested).

Protocol

Biotinylated Human  ELISA

Immobilized Human PSMA, His Tag (Cat. No. PSA-H52H3) at 2 μg/mL (100 μL/well) can bind Monoclonal Anti-Human PSMA Antibody, Human IgG1 with a linear range of 0.3-39 ng/mL (Routinely tested).

Protocol

 

活性(Bioactivity)

Measured by its ability to hydrolyze the substrate N-acetyl-L-Asp-L-Glu into N-acetyl-L-Asp and L-Glu. The L-Glu product is measured by fluorescence after its derivatization by ortho-phthaldialdehyde. The specific activity is >400 pmol/min/μg, as measured under the described conditions.

Protocol

 

背景(Background)

Prostate-specific membrane antigen (PSMA) is also known as Folate hydrolase 1 (FOLH1), Glutamate carboxypeptidase 2 (GCP2), N-acetylated-alpha-linked acidic dipeptidase I (NAALAD1), which belongs to the peptidase M28 family and M28B subfamily. FOLH1 / PSMA is stable at pH greater than 6.5. FOLH1 / PSMA is a type II transmembrane zinc metallopeptidase that is most highly expressed in the nervous system, prostate, kidney, and small intestine. FOLH1 / GCP-2 is homodimer and binds 2 zinc ions per subunit, and required for NAALADase activity. The catalytic activity of PSMA involved in releasing of an unsubstituted, C-terminal glutamyl residue, typically from Ac-Asp-Glu or folylpoly – gamma - glutamates. FOLH1 / GCP-2 / PSMA has both folate hydrolase and N – acetylated – alpha – linked - acidic dipeptidase (NAALADase) activity and has a preference for tri-alpha-glutamate peptides. GCP-2 / PSMA involved in prostate tumor progression and also exhibits a dipeptidyl-peptidase IV type activity. In vitro, cleaves Gly-Pro-AMC.
