  • 表达区间及表达系统(Source)

    Biotinylated Human PSMA, His,Avitag, premium grade (PSA-H82Qb) is expressed from human 293 cells (HEK293). It contains AA Lys 44 - Ala 750 (Accession # Q04609-1).

    Predicted N-terminus: His

    It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.

  • 蛋白结构(Molecular Characterization)

    PSMA Structure

    This protein carries a polyhistidine tag at the N-terminus, followed by an Avi tag (Avitag™).

    The protein has a calculated MW of 83.1 kDa. The protein migrates as 95-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • 偶联(Conjugate)

    Biotin

  • 标记(Labeling)

    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

    Report
  • 活性(Bioactivity)-FACS

     PSMA FACS

    2e5 of PSMA-CAR-293 cells transfected with anti-PSMA-scFv were stained with 100 μL of 1 μg/mL of Biotinylated Human PSMA, His,Avitag, premium grade (Cat. No. PSA-H82Qb) and negative control protein respectively, washed and then followed by PE-SA and analyzed with FACS (Routiney tested).

    Protocol
  • 活性(Bioactivity)-ELISA

     PSMA ELISA

    Immobilized Monoclonal Anti-Human PSMA Antibody, Human IgG1 at 2 μg/mL (100 μL/well) can bind Biotinylated Human PSMA, His,Avitag, premium grade (Cat. No. PSA-H82Qb) with a linear range of 0.2-6 ng/mL (QC 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 >200 pmol/min/μg, as measured under the described conditions (QC tested).

背景介绍

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.
