Human PSMA/FOLH1 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human PSMA/FOLH1 Protein is expressed from HEK293 with His tag at the N-Terminus. It contains Lys44-Ala750.[Accession | Q04609-1]

分子量大小(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.

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

纯度(Purity)

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

制剂(Formulation)

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

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

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

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

SEC-HPLC

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

ELISA Data

Immobilized Human PSMA, His Tag at 2μg/ml (100μl/Well) on the plate. Dose response curve for Anti-PSMA Antibody, hFc Tag with the EC50 of 7.0ng/ml determined by ELISA (QC Test).

背景(Background)

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.

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lypholized powder.
