生物描述

Accession
O94907
别名
Dickkopf-1, Dickkopf-related protein 1, Dkk-1, SK
背景
DKK1是迪克 kopf 相关蛋白家族的一员,属于分泌型蛋白,其特征是含有两个由连接区隔开的富含半胱氨酸结构域。该蛋白通过高亲和力结合低密度脂蛋白受体相关蛋白 6(LRP6),抑制 WNT 信号通路,进而阻止卷曲蛋白 - Wnt - 低密度脂蛋白受体相关蛋白 6(Frizzled-Wnt-LRP6)复合物的形成,在胚胎发育过程中发挥关键作用。当 DKK1 与细胞表面受体克门蛋白(Kremen)形成三元复合物时,还会促进低密度脂蛋白受体相关蛋白 6(LRP6)的内化与降解。此外,DKK1 可调控关节重塑与骨形成,因此与类风湿关节炎、多发性骨髓瘤等疾病的发病机制相关。从特定发育阶段开始,DKK1 还参与调控眼部发育,它通过 β- 连环蛋白介导的血小板衍生生长因子受体 α(Pdgfrα)和上皮型钙黏蛋白(E-cadherin)表达调控,对晶状体与表面外胚层的分离至关重要。

制剂
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
复溶方法
开盖前先10,000-12,000 rpm 离心 30 s;向冻干粉中加入无菌PBS,用枪头轻轻吹打混匀,重悬浓度低于 100 μg/mL;复溶之后分装放-80℃保存,避免反复冻融,如要长期储存,建议添加保护剂(如0.1% BSA、5% HSA、10% FBS等)
储存条件 (自收到货起)
For long-term storage, keep the product lyophilized at -20°C or below. Please avoid repeated freeze-thaw cycles. Stability:​ Lyophilized: 12 months (-20°C to -80°C) Reconstituted: 3 months at -80°C under sterile conditions.
