Used in biomedical research to quantify fibronectin levels in biological samples such as serum, plasma, cell culture supernatants, and tissue homogenates. Enables researchers to study cell adhesion, migration, and extracellular matrix remodeling in conditions like wound healing, inflammation, fibrosis, and cancer progression. Commonly applied in studies involving tissue regeneration, autoimmune diseases, and biomaterial interactions. Provides a reliable, sensitive, and high-throughput method for detecting fibronectin concentration, supporting both basic science and translational research.
