Human Claudin 9 (CLDN9) ELISA Kit

Quantitative measurement of claudin-9, a four-transmembrane tight junction protein of the claudin family, in human research specimens is supported by this ELISA kit supplied by Assay Genie. CLDN9 contributes to paracellular sealing across epithelial sheets and has been investigated in auditory organ of Corti studies, intestinal barrier research, and cancer models where its expression is frequently dysregulated. Validated specimen inputs for the assay include tissue homogenates, and the kit is reactive with human samples only. Components ship in a 96-assay format with all materials required to run a standard microplate workflow, including pre-coated plate, detection antibody, calibrated standards, and substrate. The colorimetric readout integrates with conventional plate-reader setups, and storage conditions plus complete protocol steps are detailed in the enclosed insert. The kit is intended for research use only and supports laboratories studying tight junction biology, paracellular permeability, or epithelial barrier function in vitro.
