CD284/TLR4(Toll样受体4)属于细胞膜模式识别受体,识别外源相关分子,启动胞内信号级联反应,参与免疫应答调控,广泛表达于多种免疫细胞。表达失衡会扰动机体免疫平衡,是免疫信号传导、机体免疫应答调控方向常用研究靶点。
Q1:这款人源 CD284/TLR4 蛋白采用什么表达平台,纯度是否稳定?
A:采用哺乳动物细胞表达系统制备,C 端 Fc 融合标签,理论分子量 97.75 kDa,蛋白具备天然糖基化修饰、构象完整,SDS-PAGE 检测纯度稳定>90%。
Q2:收到冻干 TLR4 蛋白后该怎样正确复溶使用?
A:建议使用无菌纯水复溶配制储备液,操作轻柔,避免剧烈震荡,更好维持蛋白天然构象与结合活性。
Q3:样品如何存放防止失活,延长使用周期?
A:短期频繁使用可 2–8℃保存,长期建议分装后置于 - 20℃~-80℃低温储存,收货有效期 12 个月,务必避免反复冻融。
Q4:该蛋白可开展哪些科研实验,存在哪些使用限制?
A:适用于 WB、ELISA、配体互作、抗体筛选、天然免疫相关研究,生物活性处于验证阶段,仅用于科学研究,不可应用于临床及人体相关试验。
