Used in biomedical research to measure levels of soluble guanylate cyclase (sGC) in human samples such as plasma, serum, or tissue extracts. This ELISA kit enables researchers to quantify sGC protein concentration, supporting studies on cardiovascular function, nitric oxide signaling, and diseases like pulmonary hypertension, heart failure, and sepsis. It is particularly valuable in drug development and mechanistic studies where sGC expression or release is a biomarker or therapeutic target. The assay provides high specificity and sensitivity, allowing detection of low-abundance sGC in clinical and experimental settings.
