Anti-Osteopontin N-Half (34E3) Mouse IgG MoAb

Osteopontin (OPN) is a calcium-binding glycosylated phosphoprotein secreted by many cell types. It is expressed in osteoblasts, kidney tubule cells, macrophages, activated T cells, and vascular smooth muscle cells. Osteopontin is post-translationally modified; 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. This binding activity has been localized to the N-terminal fragment of osteopontin, generated by thrombin cleavage. Osteopontin is also known as Spp-1, Apl-1, BNSP, bone sialoprotein 1, ETA-1, and minopontin.

This product is an affinity-purified IgG antibody that recognizes the N-terminal fragment of human OPN. The antibody was raised in mouse using a synthetic peptide and can be used for Western blot (WB) detection of human OPN.
