Used to measure the concentration of fibronectin in human biological samples such as plasma, serum, or cell culture supernatants. Widely applied in research settings to study extracellular matrix dynamics, tissue repair, and cell adhesion processes. Helps in assessing fibronectin levels in conditions related to inflammation, fibrosis, and cancer progression. Commonly used in clinical research to explore biomarkers for liver disease, kidney disorders, and cardiovascular conditions. Provides a reliable, sensitive, and high-throughput method for quantifying fibronectin in experimental and diagnostic studies.
