活性實驗
Osteopontin (OPN), a multifunctional phosphorylated glycoprotein, plays an important role in neutrophil recruitment and was found to induce the expression of proinflammatory chemokines including MCP-1 and MIP-1β which promote migration and recruitment of inflammatory cells. It has been reported that OPN induces MCP-1 expression through the NF-kappaB pathways in MCF-7 breast cancer cell line. To test the bioactivity of recombinant rat OPN, MCF-7 cells were seeded into 24-well plate at a density of 1x105 cells/mL , and allowed to attach overnight before treated with certain concentrations of recombinant rat OPN for 48h and MCP-1 levels in the cell supernatant were determined by ELISA (SEA087Hu). MCP-1 levels in the cell supernatant of MCF-7 cells increased significantly after stimulated with OPN which was shown in Figure1, the EC50 was 9.83 ug/ml.
用法
Reconstitute in 10mM PBS (pH7.4) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
儲存
避免反復(fù)凍融。2-8°C不超過一個月，-80°C不超過12個月。
穩(wěn)定性
熱穩(wěn)定性以損失率顯示。損失率是由加速降解試驗決定，具體方法如下：在37°C孵育48小時，沒有顯著的降解或者沉淀產(chǎn)生。保質(zhì)期內(nèi)，在適當?shù)臈l件下存儲，損失率低于5%。
