产品介绍
V01071必拓生物pTC载体,pTC vector,质粒载体图谱
pTC载体含有可与外源蛋白融合表达的大肠杆菌分子伴侣DsbC编码序列。分子伴侣DsbC同时具有二硫键异构酶活性和分子伴侣活性,可以以异构化的方式校正蛋白质中错误折叠的二硫键,从而促进外源蛋白的正确折叠,其分子伴侣活性则进一步促进外源蛋白的表达。除此之外,pTC载体还含有T7启动子,可用于外源蛋白在大肠杆菌体系中的高效表达。载体大小约为6.0kbp,卡钠霉素抗性。
产品特色
1.含有大肠杆菌DsbC序列,兼具分子伴侣和二硫键异构酶活性,可促进外源蛋白以融合的方式正确折叠与表达;
2.含有强启动子T7启动子,表达效率高。
成分
10 mM Tris(pH8.0)
保存条件
-20℃保存
注意事项
1. T7启动子强度较高,为提高可溶表达量,可以适当减少诱导剂的浓度或者降低诱导时的温度;
2.目的蛋白以融合的方式表达在DsbC下游,载体C-末端同时含有His6标签序列,可用于纯化。
