Used in cell biology research to quantify vitronectin-mediated cell adhesion activity, particularly in studies involving integrin receptors CD51/CD61 (αvβ3). The kit enables researchers to assess cell attachment, spreading, and signaling in vitro, making it valuable in wound healing, tissue engineering, and cancer metastasis studies. It is also applied in evaluating biomaterial biocompatibility by measuring how well synthetic surfaces support cell adhesion via the vitronectin pathway. Commonly used in drug development to screen compounds affecting integrin-ligand interactions.
