Product Information
KE00233 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The Osteopontin/OPN ELISA kit is to be used to detect and quantify protein levels of endogenous Osteopontin/OPN. The assay recognizes human Osteopontin/OPN. An antibody specific for Osteopontin/OPN has been pre-coated onto the microwells. The Osteopontin/OPN protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for human Osteopontin/OPN is added to detect the captured human Osteopontin/OPN protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
Osteopontin (OPN), also known as SPP1, is a secreted glycophosphoprotein that belongs to the small integrin-binding ligand N-linked glycoprotein (SIBLING) family. Originally isolated from bone, OPN has been found in kidneys, vascular tissues, biological fluids, and various tumor tissues. OPN can interact with CD44 and integrins and regulate diverse biological processes. It has a multifaceted role in bone development and remodeling, and is also involved in the inflammatory and immune response, oncogenesis and cancer progression.
