anti-PSA (human), Rabbit Monoclonal (RM323) (Biotin)

Product description: Recombinant Antibody. This antibody reacts to native human PSA (Prostate Specific Antigen), including both free (unbound) form and in a complex with ACT (alpha 1-antichymotrypsin). It may react to reduced PSA at a higher concentration. Applications: ELISA, IHC, WB. Clone: RM323. Isotype: Rabbit IgG. Formulation: Liquid. 50% Glycerol/PBS with 1% BSA and 0.09% sodium azide. Prostate-specific antigen (PSA) is a chymotrypsin-like serine protease (kallikrein family) produced by the prostate epithelium and is abundant in seminal fluid. PSA can be detected in the sera of patients with prostatic carcinoma. It is predominantly complexed to a liver-derived serine protease inhibitor, alpha-1-antichymotrypsin (ACT). A higher proportion of serum PSA is complexed to ACT in prostate cancer than in benign prostate hyperplasia. PSA is used to confirm prostatic acinar cell origin in primary and metastatic carcinoma and to rule out non-prostatic carcinoma mimics.
