Ready-to-use ELISA kits are available for the detection of RELM beta, an alias of the protein, resistin like beta. The official gene symbol is RETNLB. The kits can detect several species variants of the protein, including: human, mouse, rat, primate, guinea pig, and other mammalian. The protein, with a mass of 11.7 kDa and length of 111 residues, is reported to be secreted. It is a member of the Resistin/FIZZ family and may be known by other names, including: found in inflammatory zone 1, cysteine-rich secreted protein FIZZ2, cysteine-rich secreted A12-alpha-like protein 1, colon carcinoma-related gene protein, colon and small intestine-specific cysteine-rich protein, and FIZZ2.
