Anti-Human Osteopontin Mouse IgG MoAb

Osteopontin (OPN) is a calcium-binding glycosylated phosphoprotein secreted by many cell types, including osteoblasts, kidney tubule cells, macrophages, activated T cells, and vascular smooth muscle cells. It is also known as Spp-1, Apl-1, BNSP, bone sialoprotein 1, ETA-1, and minopontin. The molecular weight varies within the range of 44-66 kDa, depending on the level of glycosylation and phosphorylation. OPN contains an Arg-Gly-Asp (RGD) amino acid motif that is also found in other extracellular proteins that bind members of the integrin family of cell-surface receptors. A variety of OPN isoforms exist within the cell, produced by differential splicing, post-translational modification and proteolytic cleavage.

These products are affinity-purified IgG antibodies that recognize human OPN. The antibodies were raised in mouse using a synthetic peptide and can be used for Western blot (WB) detection or immunohistochemical (IHC) detection of human OPN.
