These Osteopontin ELISA kits are immunodetection tools for measuring the levels of Osteopontin in biological samples. Osteopontin is an alias of the human SPP1 gene, which encodes the protein, secreted phosphoprotein 1. Notably, Osteopontin is known to play a role in cell adhesion and inflammatory response pathways, among other functions. The SPP1 protein is 314 amino acid residues in length and 35.4 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is notably expressed in cerebrospinal fluid and urine. This protein is known to be O-glycosylated and phosphorylated. Other names for this target antigen include BNSP, BSPI, and ETA-1.
The detection range for different Osteopontin ELISA kits can vary, with some assays measuring target concentrations as low as 0.49 pg/mL and as high as 1500 ng/mL. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
