Human Dual Specificity Phosphatase 9 (DUSP9) ELISA Kit
The Human Dual Specificity Phosphatase 9 (DUSP9) ELISA Kit is specifically designed for the accurate measurement of DUSP9 levels in human serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, ensuring dependable and consistent results, making it perfect for various research applications.DUSP9 is a critical protein that plays a key role in regulating cell signaling pathways by dephosphorylating mitogen-activated protein kinases (MAPKs). It is involved in controlling various cellular processes such as cell growth, differentiation, and apoptosis.
Dysregulation of DUSP9 has been linked to various diseases, including cancer, inflammatory disorders, and neurological conditions, highlighting its importance as a valuable biomarker for studying these disorders and potential therapeutic interventions.Overall, the Human Dual Specificity Phosphatase 9 (DUSP9) ELISA Kit provides a reliable tool for researchers to accurately quantify DUSP9 levels in biological samples, enabling further insights into its roles 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.
