Used in biomedical research to detect and quantify matrix metalloproteinase-2 (MMP-2), also known as ST2, in rat samples. This ELISA kit enables researchers to measure ST2 levels in tissue extracts, serum, or cell culture supernatants, supporting studies on extracellular matrix remodeling, inflammation, cardiovascular diseases, and cancer progression in rat models. It is particularly valuable in preclinical research assessing tissue injury, fibrosis, and therapeutic responses. The assay provides high specificity and sensitivity for accurate protein detection, aiding in the understanding of disease mechanisms and biomarker development.
