Human Osteopontin (Active)

This Human Osteopontin (Active) recombinant protein from Antibodies.com represents the full-length, functionally validated human SPP1 glycoprotein, supplied at 100 µg in a liquid, unconjugated format. The Active designation indicates that bioactivity has been confirmed, commonly through a cell adhesion assay measuring integrin-mediated attachment to the conserved RGD motif. Researchers deploy this reagent as an ELISA standard, western blot control, and immunohistochemistry reference, and as a stimulus in in vitro cell migration and wound-healing studies of bone remodeling, tumor progression, cardiovascular calcification, and renal fibrosis. The vial should be aliquoted upon arrival and stored at -20 °C, with protection from repeated freeze-thaw cycles to preserve native glycosylation and downstream biological activity.
