Anti-resistin like beta antibodies are used for the immunodetection of the protein encoded by the RETNLB gene. In humans, the canonical protein has a reported length of 111 amino acid residues and a mass of 11.7 kDa. It is known to be a secreted protein. It is found to be preferentially expressed in the gastrointestinal tract, particularly the colon. A member of the Resistin/FIZZ protein family, it is a suspected to function as a hormone. Other names for this target antigen include colon and small intestine-specific cysteine-rich protein, colon carcinoma-related gene protein, cysteine-rich secreted A12-alpha-like protein 1, and C/EBP-epsilon regulated myeloid-specific secreted cysteine-rich protein precursor 2. Gene orthologs have been identified in the mouse, rat and chimpanzee species. A number of resistin like beta antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
