Used in biomedical research to quantitatively measure levels of TGFBI protein in cell culture supernatants, serum, plasma, and other biological fluids. This ELISA kit is particularly valuable in studies related to corneal dystrophies, cancer progression, and fibrosis, where TGFBI expression is altered. It enables researchers to assess the role of TGFBI in cell adhesion, migration, and apoptosis. The assay supports high sensitivity and specificity, making it suitable for monitoring disease biomarkers and evaluating therapeutic responses in experimental models.
