描述
Recombinant Human Integrin alpha 2B beta 3 (ITGA2B&ITGB3) Heterodimer Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Leu32-Arg993(ITGA2B) acidic tail & GLy27-Asp718(ITGB3) basic tail [Accession | P08514-1(ITGA2B)&P05106-1(ITGB3)].
储存
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.未开盖的干粉蛋白在 -20°C至-80°C可保存12个月;
复溶之后,蛋白溶液在-20°C及以下可保存3个月,在2-8℃可保存1周。
生物活性
Immobilized Abciximab at 1μg/ml (100μl/well) on the plate. Dose response curve for Human ITGA2B&ITGB3, His Tag with the EC50 of 16.7ng/ml determined by ELISA.
复溶
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底,如果粉末浮起,开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL(请注意蛋白复溶浓度不能低于0.1 mg/mL),室温平衡5-10 min保证充分溶解,复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存,建议复溶时添加载体蛋白或者稳定剂(如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖),同时将复溶后的蛋白溶液按照需求进行分装,储存于-20°C至-80°C,随取随用,避免反复冻融。
请在蛋白复溶计算器中输入蛋白总质量和所需终浓度,快速计算您需要添加溶液的体积吧!
Glanzmann thrombasthenia (GT) is characterized by mucocutaneous bleeding due to platelets that fail to aggregate in response to physiologic stimuli. GT, a rare inherited disease, is caused by quantitative or qualitative deficiencies of αIIbβ3, an integrin receptor for adhesive proteins. Coded by the ITGA2B and ITGB3 genes, αIIbβ3 mediates platelet-to-platelet attachment, aggregation and clot retraction.
