Human PSMA/FOLH1 Protein

Product Info

Recombinant Human PSMA/FOLH1 Protein is expressed from Expi293 with His tag at the N-terminal. It contains Lys44-Ala750.[Accession | Q04609]

Molecular Weight

The protein has a predicted MW of 80.6 kDa. Due to glycosylation, the protein migrates to 90-110 kDa based on Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC


Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.


Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.


The product should be stored at -70℃ or -20℃.

Assay Data
Tris-Bis PAGE

Human PSMA on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.


The purity of Human PSMA is greater than 95% as determined by SEC-HPLC.


Immobilized Human PSMA at 2μg/ml (100μl/Well) on the plate. Dose response curve for Anti-PSMA Antibody, hFc Tag with the EC50 of 15.2ng/ml determined by ELISA.


Prostate-specific membrane antigen (PSMA) is an enzyme that in humans is encoded by the FOLH1 (folate hydrolase 1) gene, also known as Glutamate carboxypeptidase II (GCPII). Human PSMA is highly expressed in the prostate, roughly a hundred times greater than in most other tissues. In some prostate cancers, PSMA is the second-most upregulated gene product, with an 8- to 12-fold increase over levels in noncancerous prostate cells.
