Prostate specific antigen (PSA) is a glycoprotein with a molecular mass of 33-34 kD. Clone ErPr8 is directed against a 35 kD protein identical to PSA. PSA is biochemically and immunologically distinct from prostatic acid phosphatase. It is restricted to the cytoplasm of acinar and ductal epithelia of normal, benign or malignant prostate tissue. Staining with this antibody is confined to the cytoplasm of prostatic acinar and ductal epithelium. This antibody is useful for determining if an isolated metastasis is of prostatic origin. Since PSA is released by prostatic tumors, it is also a valuable serum marker of neoplasia.
