Background :
107.1A4 is a Mouse monoclonal IgG1/k antibody derived by fusion of SP2/0-Ag14 Mouse myeloma cells with spleen cells from an immunized Mouse, using a two-phase immunization protocol involving the prostate cancer cell line LNCaP.

Prostate specific antigen (PSA) is the most widely used marker of prostate cancer. Immunoassays for PSA using monoclonal (MAb) or polyclonal antibodies have clinical applications, such as monitoring and early detection of prostate cancer. However, PSA is not a perfect tumor marker because Serum levels often are elevated in men with benign prostatic hyperplasia, prostatitis and other nonmalignant disorders and also because levels are not always elevated in individuals with early prostate cancer. 107-1A4 is a new prostate cancer-reactive MAb which can identify additional proteins that could be of value for the diagnosis and treatment of prostate cancer. It shows selective reactivity to prostate epithelial membrane antigens. <
Product :
Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide. Formulation: Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.
Specificity :
107.1A4 recognizes an antigen, which appeared to be distinct from those previously described and shows specific tumor targeting in preliminary in vivo studies. MAb 107-1A4 is suggested to recognize a distinct conformational and unique epitope in the extracellular domain of PSMA. PSMA is a type II membrane glycoprotein of 100kDa that has a short intracellular N-terminal domain (residues 1 to 18), a transmembrane region (residues 19 to 43) and a large extracellular domain consisting of residues 44 to 750.
Applications :
MAb 107-1A4 could not be used in Western blot, is useful for immunohistochemistry on frozen and paraffin-embedded tissues, immunocytochemistry, flow cytometry and ELISA. Optimal antibody dilution should be determined by titration; recommended range is 1:100 – 1:1000 for immunohistochemistry with avidin-biotinylated Horseradish peroxidase complex (ABC) as detection reagent.
Storage :
The antibody is shipped at ambient temperature and may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.
