Endothelin 1 (EDN1) is a potent vasoconstrictor peptide that plays a key role in cardiovascular physiology and pathology. This 21-amino acid peptide is primarily produced by vascular endothelial cells and acts through endothelin receptors to regulate vascular tone, blood pressure, and cardiac function. Elevated endothelin 1 levels are associated with various cardiovascular diseases, including hypertension, atherosclerosis, and heart failure. This makes it an important biomarker for cardiovascular research and clinical studies.
The Human Endothelin 1,ET-1 ELISA Kit (CSB-E07007h) provides quantitative measurement of endothelin 1 in human samples. This sandwich ELISA works with serum, cell culture supernates, urine, and saliva samples. Detection range spans 3.12 pg/mL to 200 pg/mL with sensitivity of 0.78 pg/mL. The assay requires 50-100 μL sample volume, operates at 450 nm detection wavelength, and can be completed within 1-5 hours.
