The Human Angiotensin I (ANG I) ELISA Kit is specifically designed for the precise measurement of ANG I levels in human serum, plasma, and cell culture supernatants. This kit provides outstanding sensitivity and specificity, ensuring accurate and consistent results for a variety of research applications.ANG I is a key molecule in the renin-angiotensin system, playing a vital role in regulating blood pressure and fluid balance. Abnormal levels of ANG I have been associated with various cardiovascular conditions, making it a valuable biomarker for studying and developing treatments for these diseases.
Overall, the Human ANG I ELISA Kit is a valuable tool for researchers studying cardiovascular health and looking to better understand the role of ANG I in disease processes. Its reliability and accuracy make it an essential component of any laboratory investigating the renin-angiotensin system.

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 condition. 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.
