Human XIRP2 ELISA Kit (HUFI05623)

The XIRP2 protein (Xin actin-binding repeat-containing protein 2) is a striated muscle-specific cytoskeletal regulator highly expressed in cardiac tissue, where it localizes to intercalated discs and costameres. Loss-of-function mutations in the XIRP2 gene have been associated with familial dilated cardiomyopathy and atrial fibrillation, positioning circulating XIRP2 as an emerging biomarker for myocardial injury and remodeling research. Assay Genie provides this research-use-only immunoassay configured for quantitative measurement of human XIRP2 in clinical research samples, helping investigators track expression changes in longitudinal studies of heart failure progression. Each kit includes pre-coated microplate wells, calibration standards, biotinylated detection antibody, streptavidin-HRP conjugate, and substrate solution. For best results, aliquot standards and reconstituted reagents, then freeze at -80°C to limit freeze-thaw cycles and preserve signal stability.
