PSA Antibody (A67-B/E3) is a mouse monoclonal IgG1 kappa light chain antibody that detects prostate specific antigen (PSA) of human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). Anti-PSA antibody (A67-B/E3) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. Prostate specific antigen, also known as kallikrein-related peptidase 3 (KLK3), is a serine protease primarily produced in the prostate gland, where PSA plays a crucial role in the liquefaction of semen by hydrolyzing semenogelin I, a major protein in seminal plasma. This enzymatic activity is vital for male fertility, as PSA allows sperm to swim freely after ejaculation. Elevated levels of PSA in the blood are often associated with prostate cancer, making PSA a key biomarker for early detection and monitoring of the disease. Additionally, PSA has been found in other tissues, including breast tissue, highlighting PSA′s potential role in various cancers. PSA monoclonal antibody (A67-B/E3) accurately detects this important protein across multiple applications, making PSA (A67-B/E3) antibody an essential tool for researchers studying prostate health and disease.
