Product details:
Human Osteopontin ELISA Kit ab100618 is a sandwich ELISA to measure Human Osteopontin in serum, plasma, cell culture supernatant, urine, milk with a sensitivity of 50 pg/ml.
How the assay works
This assay employs an antibody specific for Human Osteopontin coated on a 96-well plate. Standards and samples are pipetted into the wells and Osteopontin present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human Osteopontin antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Osteopontin bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
Assay Specificity
Our ELISA kits are rigorously validated to ensure the highest level of consistency and reproducibility. Please check the protocol booklet for more details

Osteopontin also known as OPN or secreted phosphoprotein 1 (SPP1) is a glycoprotein with a molecular weight of approximately 44 to 75 kDa depending on its post-translational modifications. Osteopontin is characteristically expressed in bone but is also present in various body tissues including kidney liver and immune system cells. This multifunctional protein interacts with cell surface receptors such as integrins and CD44 playing an important role in cell signaling and extracellular matrix interactions. Researchers often study it using osteopontin western blot or osteopontin ELISA kit to understand its expression patterns and roles.
Biological function summary
Osteopontin affects cell adhesion migration and survival. It does not form part of a known large complex but interacts closely with its integrin receptors. Osteopontin modulates immune responses and aids in bone remodeling by affecting osteoclast and osteoblast functions. It is also influential in inflammation processes where it orchestrates the recruitment and activation of macrophages. The osteopontin function is significant in both physiological processes and pathologies marking it as an important protein to study in numerous biological contexts.
Pathways
Osteopontin is integral to both the bone remodeling and immune response pathways. It collaborates with proteins like osteocalcin and matrix metalloproteinases within these processes. In the bone remodeling pathway osteopontin mediates communication between osteoclasts and osteoblasts impacting bone resorption and formation. In the immune response pathway it coordinates with cytokines such as interleukin-6 to modulate immune cell activities. Its roles in these pathways indicate its multifunctional nature and its impact across different biological systems.
Osteopontin links to cancer and cardiovascular diseases. It facilitates tumor progression and metastasis by interacting with proteins such as vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9). In cardiovascular diseases osteopontin influences atherosclerosis development through interactions with inflammatory cytokines and contributes to plaque stability. These disease associations highlight the importance of osteopontin as both a therapeutic target and a biomarker for disease progression and prognosis.
