产品名称 SOX2 Recombinant Rabbit mAb 产品介绍
商品属性 产品介绍This intronless gene encodes a member of the SRY-related HMG-box (SOX) family of transcription factors involved in the regulation of embryonic development and in the determination of cell fate. The product of this gene is required for stem-cell maintenance in the central nervous system, and also regulates gene expression in the stomach. Mutations in this gene have been associated with optic nerve hypoplasia and with syndromic microphthalmia, a severe form of structural eye malformation. This gene lies within an intron of another gene called SOX2 overlapping transcript (SOX2OT). [provided by RefSeq, Jul 2008].

PubMedPubMed 靶点与功能 P62(Sequestosome 1,SQSTM1)是一种多功能支架蛋白,通过其UBA结构域结合泛素化蛋白,介导异常蛋白通过自噬-溶酶体途径降解,同时参与NF-κB信号激活、Nrf2抗氧化通路调控及细胞凋亡抑制。其功能异常与癌症(如肝癌、肺癌)、神经退行性疾病(如帕金森病) 及代谢综合征直接相关,是自噬 flux 检测和疾病机制研究的关键标志物。 实验操作关键要点 WB优化(自噬 flux 检测): 样本处理:细胞需用含蛋白酶抑制剂(PMSF+抑肽酶) 的RIPA裂解液冰上裂解30分钟,14000g离心20分钟取上清;若检测自噬流,需同步设置氯喹(CQ,50μM)处理组作为阳性对照(抑制溶酶体降解,P62累积); 电泳条件:10% SDS-PAGE凝胶,恒压80V浓缩胶、120V分离胶,确保62kDa主条带与修饰型条带分离; 抗体孵育:一抗推荐1:2000稀释(5%脱脂奶粉+TBST),4℃摇床孵育过夜,HRP标记二抗(山羊抗兔)1:5000室温孵育1小时。 IHC-P注意事项(肿瘤组织样本): 抗原修复:采用EDTA缓冲液(pH9.0) 高压修复5分钟(针对福尔马林固定石蜡切片),增强胞质信号; 阳性对照:推荐使用肝癌组织切片(肿瘤细胞胞质呈棕黄色颗粒状阳性,伴核周聚集); 封闭处理:5%驴血清+0.3% Triton X-100室温封闭45分钟,配合3% H₂O₂阻断内源性过氧化物酶(15分钟)。 IF双标实验(自噬共定位研究): 推荐与LC3B抗体共染(自噬小体标志物),使用Alexa Fluor 488(绿色,标记P62)和594(红色,标记LC3B),激光共聚焦观察二者共定位斑点(自噬降解复合物)。 公司正在出售的产品
