Biocare Medical, LLC has been awarded United States Patent No. US 8,852,592 for the anti-PAX8 mouse monoclonal antibody, clone [BC12]. This mouse monoclonal PAX8 antibody [BC12] has been designed to target a restricted epitope and exhibits higher specificity and provides sharper staining than the PAX8 rabbit polyclonal antibody. This clone was developed in-house and is exclusive to Biocare Medical.

PAX8 is expressed in a high percentage of renal cell carcinomas and ovarian cancers. Unlike the polyclonal PAX8, this mouse monoclonal antibody does not stain B-cells, and does not recognize epitopes of pancreatic origin and neuroendocrine cells in stomach and colon; thus providing superior specificity. The expression of the mouse monoclonal PAX8 target antigens was found in normal kidney, thyroid and cervix, but was not identified in normal ovary. By Western blot, [BC12] has been shown to recognize PAX8 and not PAX2, PAX5 or PAX6 proteins. PAX8 stains nuclei exclusively and performs well in formalin-fixed paraffin-embedded tissues. Further details are described in the following paper: Tacha D, et al. Appl Immunohistochem Mol Morphol 2013 Jan; 21(1):59-63.
