The Human Endothelin-1 (EDN1) ELISA Kit is specially designed for the precise measurement of endothelin-1 levels in human samples such as serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit delivers accurate and consistent results, making it an excellent choice for various research applications.Endothelin-1 is a key peptide that plays a crucial role in regulating blood vessel tone and blood pressure. Dysregulation of endothelin-1 levels has been associated with various cardiovascular diseases, including hypertension, atherosclerosis, and heart failure.
By accurately measuring endothelin-1 levels, researchers can gain valuable insights into the pathophysiology of these conditions and explore potential therapeutic interventions.The Human Endothelin-1 (EDN1) ELISA Kit is a valuable tool for studying endothelin-1 biology and its implications in cardiovascular health, providing researchers with a reliable and efficient method for measuring endothelin-1 levels in human samples.

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.
