Osteopontin/OPN Protein, a crucial non-collagenous bone protein, binds strongly to hydroxyapatite, integral to the mineralized matrix.It likely plays a vital role in mediating cell-extracellular matrix interactions.Moreover, as a cytokine, OPN efficiently induces interferon-gamma and interleukin-12 production while inhibiting interleukin-10, pivotal in promoting type I immunity.Osteopontin/OPN Protein, Mouse (P.pastoris, His) is the recombinant mouse-derived Osteopontin/OPN protein, expressed by P.pastoris , with N-6*His labeled tag.
