Rat TJP1 (Tight Junction Protein 1) ELISA Kit (RTES00821)

Tight Junction Protein 1 (TJP1), also referred to as Zonula Occludens-1 (ZO-1), is a peripheral scaffolding protein critical to the assembly and regulation of epithelial and endothelial tight junctions. Quantification of TJP1 in rat tissue and biofluid specimens underpins research into barrier integrity, intestinal permeability, blood-brain barrier function, and the cellular mechanisms of inflammatory and epithelial injury.

The Assay Genie TJP1 rat ELISA provides a colorimetric readout and is configured as a 96-assay kit intended for research use only, with reactivity verified against rat samples. Reagents are supplied as a complete set, and the 96 assays format supports multiple replicates and standard curves across one or more microplates, enabling reliable side-by-side comparison of experimental and control cohorts.

Common laboratory applications include studies of gastrointestinal barrier dysfunction, neurovascular permeability, epithelial-mesenchymal transition models, and investigation of tight junction remodeling in disease states. The assay is intended for in vitro research and uses a single-use microplate format suitable for batch processing of experimental samples within a working session.
