FIR Antibody (B-5) is a mouse monoclonal IgG2b light chain antibody that detects FIR in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). FIR, or FBP interacting repressor, plays a crucial role in regulating the expression of the c-myc gene by interacting with the FUSE-binding protein, which is essential for c-myc activation. This regulation is vital because c-myc is a key player in cell proliferation and growth, and its dysregulation can lead to oncogenesis. FIR is predominantly expressed in various tissues, including the spleen, thymus, prostate, small intestine, colon, and peripheral blood leukocytes, with particularly high levels found in the testis and ovary, indicating potential involvement in reproductive biology. Anti-FIR antibody (B-5) provides reliable detection of this important protein, facilitating research into its role in gene regulation and implications in cancer biology and other diseases.
