Anti-SPP1 Antibody

Antibodies.com offers this rabbit polyclonal IgG antibody against SPP1 (Secreted Phosphoprotein 1), the gene that encodes osteopontin, a secreted phosphoglycoprotein widely studied for its role in bone remodeling, cell-matrix adhesion, immune cell signaling, and tumor microenvironment biology.

Supplied as 100 µl of unconjugated antiserum validated for Western blot, immunohistochemistry, and flow cytometry on human samples, the reagent supports research into osteopontin-driven processes including metastatic colonization, fibrosis, and inflammatory signaling. Researchers pair the antibody with HRP- or fluorophore-conjugated secondary reagents of rabbit IgG specificity.

For long-term use, store aliquots frozen at -20°C and avoid repeated freeze-thaw cycles to preserve binding activity. Each lot is affinity-purified against the SPP1 immunogen and characterized for specificity on human osteopontin-expressing cell lines.
