Used for the quantitative measurement of Big Endothelin (BigET) in biological samples such as plasma, serum, or cell culture supernatants. This ELISA research kit enables researchers to study endothelial function and assess conditions related to cardiovascular diseases, including hypertension, heart failure, and pulmonary arterial hypertension. It is widely applied in preclinical research and drug development to monitor changes in endothelin levels in response to therapeutic interventions. The assay supports high sensitivity and specificity, making it suitable for detecting low concentrations of BigET in small sample volumes. Commonly used in academic laboratories, pharmaceutical research, and clinical studies focused on vascular biology and endothelial dysfunction.
