Rat Claudin 3 (CLDN3) ELISA Kit

Quantitative measurement of rat Claudin-3 (CLDN3) is supported by this colorimetric ELISA kit from Assay Genie, intended for research into tight junction biology and epithelial barrier function. Claudin-3 is a transmembrane protein of the claudin family that contributes to paracellular seal formation in epithelial and endothelial monolayers, making it a useful biomarker in studies of tissue barrier integrity, mucosal permeability, and tight junction remodeling under inflammatory or pathological challenge. The kit is supplied as a 96-assay pack and is validated for use with tissue homogenates and cell lysates of rat origin. Researchers commonly apply this assay to monitor CLDN3 expression in gastrointestinal, renal, and reproductive tract tissues where the protein is abundantly expressed, supporting work on epithelial sheet permeability, gut barrier dysfunction, and tight junction protein quantification. Reagents should be stored refrigerated at the temperatures specified in the package insert to preserve standard curve performance across runs. Intended for research use only; not validated for clinical or diagnostic procedures.
