Rat Claudin 4 (CLDN4) ELISA Kit

Claudin 4 (CLDN4) is a transmembrane tight junction protein central to epithelial barrier integrity, with established roles in paracellular transport regulation and tumor biology research. This quantitative immunoassay from Assay Genie enables measurement of endogenous CLDN4 in rat tissue homogenates, cell lysates, and related biological specimens, supporting studies of intestinal, renal, and hepatic epithelial function in rat model systems. The kit produces an absorbance-based signal proportional to target concentration and arrives complete with all required reagents, microtiter plate, diluents, wash buffer, and a recombinant CLDN4 standard for curve generation. Standard laboratory absorbance readers handle data acquisition, and a four-parameter logistic curve fit provides quantitative sample values against the standard curve. The assay is configured specifically for rat samples, which is important for investigators using rat disease models of colitis, diabetic nephropathy, or chemically induced epithelial injury. Each kit is intended for research use only, is not approved for diagnostic or therapeutic procedures, and should be refrigerated between uses with protection from light to preserve antibody and conjugate activity throughout its stated shelf life.
