Human Fibronectin Type III Domain Containing Protein 5 (FNDC5) ELISA Kit

Irisin, the cleaved extracellular fragment of the transmembrane precursor FNDC5, is a myokine secreted by skeletal muscle during physical activity and has been linked to energy expenditure, white adipose tissue browning, and glucose homeostasis. This Assay Genie quantitative immunoassay targets human FNDC5 on a 96-assay plate with antibody-based detection. Researchers in metabolic disorders, exercise physiology, type 2 diabetes, obesity, and cardiometabolic studies use this kit to quantify circulating irisin in patient cohorts and exercise intervention trials. Each kit includes pre-coated wells, reference standards for generating standard curves, and a complete buffer set. Refrigerated storage preserves reagent activity over the 12 month shelf life, and aliquoting samples prior to storage helps minimize freeze-thaw degradation of the target analyte. Synonyms tracked by the kit include FRCP2 and fibronectin type III repeat-containing protein 2; the UniProt reference is Q8NAU1.
