The Rat Claudin-4 (CLDN4) ELISA Kit is specifically designed for the quantitative detection of Claudin-4 levels in rat serum, plasma, and cell culture supernatants. This kit offers superior sensitivity and specificity, ensuring precise and consistent results for a variety of research purposes.Claudin-4 is a critical protein involved in the maintenance of tight junctions in epithelial cells, playing a key role in regulating paracellular permeability. Dysregulation of Claudin-4 has been implicated in various diseases including inflammatory bowel disease, cancer, and hepatitis, making it a valuable biomarker for disease research and therapeutic development.
With its reliable performance and accuracy, the Rat Claudin-4 ELISA Kit is an essential tool for scientists studying epithelial barrier function, intestinal permeability, and the role of tight junction proteins in disease pathology. Get your research off to a strong start with this cutting-edge ELISA kit from Assay Genie.

Linearity:
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of the index and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Intra-assay Precision:
Intra-Assay: CV <10%. 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision:
Inter-Assay: CV <12%. 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
Stability:
The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage conditions. Note: To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
