Target

  • RelevancePSCA (Prostate Stem Cell antigen) is a cell surface antigen, which is overexpressed in ~40% of primary prostate cancers and in as many as 100% of metastatic ones. PSCA is also overexpressed in a majority of transitional cell and pancreatic carcinomas. Antibody directed against PSCA inhibits tumorigenesis, slows tumor growth, prolongs survival and prevents metastasis in a preclinical zenograft model indicating that PSCA may have utility as a prognostic marker and/or therapeutic target in prostate cancer.
  • Cellular localizationCell membrane; Lipid-anchor, GPI-anchor.

Anti-PSCA antibody images

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human prostate carcinoma tissue labeling PSCA with ab64919. Tissue was fixed with formaldehyde and blocked with 3% BSA for 0.5 hour at 37°C; heat mediated antigen retrieval was performed using  a citrate buffer (pH6). Samples were incubated with primary antibody (1/25) for 1 hours at 37°C. A Peroxidase-conjugated Goat anti-rabbit polyclonal (ready to use) was used as the secondary antibody.

  • All lanes : Anti-PSCA antibody (ab64919) at 1 µg/ml

    Lane 1 : HepG2 (Human hepatocellular liver carcinoma cell line) Whole Cell Lysate
    Lane 2 : DU 145 (Human prostate carcinoma cell line) Whole Cell Lysate

    Lysates/proteins at 10 µg per lane.

    Secondary
    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Predicted band size : 13 kDa
    Observed band size : 18 kDa (why is the actual band size different from the predicted?)
