Description
Vitronectin mediates cell adhesion, migration, and matrix remodeling through integrin and urokinase plasminogen activator receptor interactions, making it a critical component in wound healing, cancer invasion, and thrombosis models. This full-length mature protein (aa 20–478) demonstrates functional activity with an ED50 of 2–10 μg/mL in supporting NIH3T3 fibroblast adhesion, providing a quantitative benchmark for coating concentrations in cell attachment assays, integrin-binding studies, and 3D culture scaffold applications. Mammalian expression preserves the native glycosylation and disulfide architecture essential for receptor recognition, enabling researchers to model physiologically relevant ECM interactions in fibrosis progression, tumor cell invasion, and wound healing experiments. The combination of >95% purity and ≤10 EU/mg endotoxin satisfies the quality criteria typical for sensitive cell-based assays and can serve as a coating antigen for validating anti-vitronectin antibodies in immunoassays.
