The Human Urotensin-2 (UST2) ELISA Kit is specifically designed for the precise measurement of urotensin-2 levels in human serum, plasma, and cell culture supernatants. This highly sensitive and specific kit ensures accurate and reproducible results, making it an invaluable tool for a variety of research applications.Urotensin-2 is a key peptide involved in various physiological processes, including cardiovascular regulation, smooth muscle contraction, and blood pressure regulation. Dysregulation of urotensin-2 levels has been associated with cardiovascular diseases, kidney disorders, and other pathological conditions, making it a crucial biomarker for studying these diseases and potentially developing new therapeutic interventions.
This ELISA kit provides researchers with a reliable and efficient method for quantifying urotensin-2 levels in human samples, allowing for comprehensive analysis and deeper insights into the role of this peptide 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.
