Osteopontin ELISA Kit (Mouse)


Mouse osteopontin ELISA kit is a method for quantitative determination of mouse osteopontin (OPN) in plasma, urine and cell culture media. This assay has a minimum sensitivity detection limit of 0.15 ng/ml.


Osteopontin (OPN) is a glycosylated calcium binding highly acidic phosphoprotein which is secreted by a number of different cell types such as: macrophages, osteoblasts, vascular smooth muscle cells, activated T-cells and kidney tubule cells. Its molecular weight can range from 44-66 kDa depending on phosphorylation and glycosylation. A key feature of osteopontin is the presence of Arg-Gly-Asp (RGD) amino acid sequence, this sequence is also found in vitronectrin, fibronectin and various other integrin family members. Various molecular forms of OPN are found to exist in vivo due to the effects of phosphorylation, glycosylation, RNA splicing and sulfation. However, both thrombin and OPN often localised together at sites of inflammation, injury, tumor cells and angiogenesis.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
