Used in research settings to quantify mouse fibronectin levels in biological samples such as serum, plasma, cell culture supernatants, and tissue homogenates. This ELISA kit is particularly valuable in studies related to extracellular matrix dynamics, wound healing, inflammation, fibrosis, and cancer progression, where fibronectin plays a key role in cell adhesion, migration, and tissue remodeling. The assay enables high sensitivity and specificity, allowing researchers to monitor changes in fibronectin expression under experimental conditions, assess disease models in mice, and evaluate therapeutic interventions targeting matrix proteins.
