Used in biomedical research to quantify Biglycan (BGN), a proteoglycan involved in extracellular matrix organization and inflammatory processes. This ELISA kit enables researchers to measure BGN levels in biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. It is commonly applied in studies related to fibrosis, osteoarthritis, cardiovascular diseases, and cancer progression, where BGN expression is altered. The assay provides high sensitivity and specificity, supporting accurate detection for both basic research and diagnostic development.
