The Human CLDN1 (Claudin-1) ELISA Kit is specifically designed for the accurate measurement of CLDN1 levels in human biological samples such as serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, ensuring dependable and consistent results suitable for various research applications.Claudin-1 is a key protein involved in the tight junctions of epithelial and endothelial cells, playing a critical role in maintaining barrier functions and cell polarity.
Dysregulation of CLDN1 has been associated with various diseases such as cancer, inflammatory bowel disease, and viral infections, making it a valuable biomarker for studying these conditions and developing potential treatments.Overall, the Human CLDN1 ELISA Kit offers a reliable and efficient solution for researchers to accurately quantify CLDN1 levels in human samples, enabling further investigation into the role of Claudin-1 in health and disease.

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.
