Anti-Osteopontin Antibody

Osteopontin (OPN, also known as SPP1) is a secreted phosphoglycoprotein central to bone remodeling, cell adhesion, inflammation, and tumor progression. This Antibodies.com polyclonal reagent was raised in rabbit and is supplied as an unconjugated IgG in liquid format at 100 µg, validated for western blot (WB) and immunocytochemistry (ICC) on mouse samples. Store at -20 °C in working aliquots and limit freeze-thaw cycles to preserve binding activity; protect from light during handling. Investigators working on extracellular matrix biology, osteoclast differentiation, or cancer metastasis pathways rely on anti-osteopontin antibodies to detect both secreted and cell-associated SPP1 in cell lysates and fixed cell preparations.
