Used in biomedical research to quantify levels of human matrix lysin (ST3), also known as stromelysin-3, in biological samples such as serum, plasma, and tissue extracts. This kit is particularly valuable in studies related to tissue remodeling, cancer progression, and inflammatory diseases, as ST3 plays a key role in extracellular matrix degradation and tumor invasion. Researchers use this assay to investigate the involvement of ST3 in breast cancer, colorectal cancer, and other malignancies, helping to assess its potential as a biomarker for disease prognosis and therapeutic response. The ELISA format allows for high sensitivity and specificity, making it suitable for both clinical and experimental settings.
