产品名称 RalA Recombinant Rabbit mAb 产品介绍
商品属性 产品介绍Multifuntional GTPase involved in a variety of cellular processes including gene expression, cell migration, cell proliferation, oncogenic transformation and membrane trafficking. Accomplishes its multiple functions by interacting with distinct downstream effectors. Acts as a GTP sensor for GTP-dependent exocytosis of dense core vesicles. Plays a role in the early stages of cytokinesis and is required to tether the exocyst to the cytokinetic furrow. The RALA-exocyst complex regulates integrin-dependent membrane raft exocytosis and growth signaling. Key regulator of LPAR1 signaling and competes with ADRBK1 for binding to LPAR1 thus affecting the signaling properties of the receptor. Required for anchorage-independent proliferation of transformed cells.

PubMedPubMed 靶点与功能 S6核糖体蛋白(RPS6,40S ribosomal protein S6)是40S核糖体亚基的组成部分,通过磷酸化修饰(如Ser235/236、Ser240/244位点)参与mRNA翻译起始调控,是mTOR信号通路的关键下游效应分子。其磷酸化激活可促进核糖体生物合成和细胞周期进展,与细胞增殖、肿瘤发生(如乳腺癌、结直肠癌) 及代谢疾病密切相关,是研究细胞生长调控的重要标志物。 实验操作关键要点 WB优化(肿瘤细胞样本): 样本处理:使用含磷酸酶抑制剂(如PhosSTOP) 的RIPA裂解液冰上裂解30分钟,12000g离心15分钟取上清;推荐使用HeLa细胞系(RPS6高表达)作为阳性对照; 电泳条件:10% SDS-PAGE凝胶,恒压80V浓缩胶、120V分离胶,电泳时间90分钟确保29kDa条带分离; 抗体孵育:一抗推荐1:1000稀释(5%脱脂奶粉+TBST),4℃摇床孵育过夜,HRP标记二抗(山羊抗小鼠)1:5000室温孵育1小时,曝光时间30-60秒。 IHC-P注意事项(结肠癌组织): 抗原修复:采用柠檬酸钠缓冲液(pH6.0) 微波修复20分钟(95℃),增强核周/胞质信号; 阳性定位:肿瘤细胞胞质呈棕黄色颗粒状阳性,正常组织中表达较低; 封闭处理:5%羊血清+TBST室温封闭30分钟,减少非特异性结合。 IF双标实验(mTOR通路研究): 推荐与磷酸化S6K1(p-S6K1,Thr389) 共染,使用Alexa Fluor 488(绿色,标记RPS6)和594(红色,标记p-S6K1),激光共聚焦观察二者共定位(激活的mTOR信号通路)。 公司正在出售的产品
