Human Claudin 4 (CLDN4) ELISA Kit

The Assay Genie Human Claudin 4 (CLDN4) ELISA Kit enables quantitative measurement of CLDN4, a tight junction transmembrane protein critical for epithelial barrier integrity and paracellular permeability. CLDN4 is frequently studied in oncology research, where its overexpression is associated with pancreatic ductal adenocarcinoma, ovarian carcinoma, gastric cancer, and colorectal tumors, and it also serves as the high-affinity receptor for Clostridium perfringens enterotoxin (CPE).

This microplate-format kit is supplied with pre-coated wells and uses a colorimetric readout compatible with standard laboratory plate readers, and the assay is validated specifically for human CLDN4 detection with no cross-reactivity against related rodent claudin homologues. Reconstituted reagents should be stored refrigerated to preserve antibody activity, and the kit is intended for research use only, supporting studies in cell biology, cancer biology, and epithelial physiology.
