Human Resistin Like Beta (RETNLb) ELISA Kit

Resistin-like molecule beta (RETNLb, also known as RELM-beta or FIZZ2) is a cysteine-rich secreted peptide most strongly expressed in goblet cells of the colon and small intestine, where it modulates mucosal barrier function, Th2-skewed inflammatory responses, and host defence against intestinal helminths. Quantifying this protein in circulation and tissue homogenates supports research into inflammatory bowel disease, colitis-associated tumorigenesis, metabolic dysfunction, and gastrointestinal mucosal immunity.

This quantitative kit from Assay Genie is supplied as 96 assays with all key reagents included, so laboratories can generate RETNLb measurements in standard human liquid sample matrices without needing to assemble working solutions from separate components.

Intended for research use only, the kit serves academic, clinical research and pharmaceutical discovery laboratories studying gastrointestinal biology, host-microbe interactions, or secreted adipokine and cytokine networks. Standards and detection reagents are pre-titrated for the supplied protocol, supporting reproducible absorbance-based readouts on standard microplate readers.
