Rat osteopontin ELISA kit is intended for measuring quantitative concentrations of rat osteopontin (OPN) using EDTA plasma, cell culture media or urine samples. This assay has a minimum sensitivity detection limit of 0.01 ng/ml.
Osteopontin (OPN) is a glycosylated highly acidic calcium binding phosphoprotein which is released by vascular smooth muscle cells, kidney tubule cells, osteoblasts and activated T-cells. Due to glycosylation and phosphorylation the molecular weight of OPN can range from 44-66 kDa. The amino acid sequence Arg-Gly-Asp (RGD) is present and different forms of osteopontin can be found to be present because of RNA splicing, glycosylation, sulfation and phosphorylation. Both OPN and thrombin localise together at sites of injury, angiogenesis, inflammation and tumor cells.
The minimum sensitivity detection limit of OPN using current rat osteopontin ELISA kit is 0.01 ng/ml. The dynamic range for this assay is 0.07 – 4.75 ng/ml.
