产品名称 S100A1 Rabbit pAb 产品介绍
商品属性 产品介绍The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein may function in stimulation of Ca2+-induced Ca2+ release, inhibition of microtubule assembly, and inhibition of protein kinase C-mediated phosphoryla

PubMedPubMed 靶点与功能 FSP-1(Fibroblast Specific Protein 1,S100A4)是S100钙结合蛋白家族成员,通过调控细胞骨架重塑和细胞外基质(ECM)降解参与成纤维细胞活化、上皮-间质转化(EMT) 过程。其高表达与肝纤维化、肺纤维化及肿瘤侵袭转移密切相关,是活化成纤维细胞(肌成纤维细胞)和肿瘤相关成纤维细胞(CAF)的特异性标志物,也是评估纤维化程度和肿瘤微环境的关键指标。 实验操作关键要点 IHC-P优化(纤维化组织样本): 样本处理:福尔马林固定石蜡切片需用柠檬酸钠缓冲液(pH6.0) 微波修复20分钟(95℃),增强胞质信号; 抗体孵育:一抗推荐1:100稀释(5%羊血清+TBST),4℃湿盒孵育过夜,HRP标记二抗(山羊抗小鼠)1:500室温孵育30分钟; 阳性对照:推荐使用肝纤维化模型小鼠肝组织(汇管区成纤维细胞胞质呈棕黄色阳性)。 WB检测要点(成纤维细胞样本): 样本处理:使用含蛋白酶抑制剂(1mM PMSF) 的RIPA裂解液冰上裂解30分钟,12000g离心15分钟取上清; 电泳条件:15% SDS-PAGE凝胶(因分子量小),恒压80V浓缩胶、120V分离胶,确保11kDa主条带分离; 转膜条件:PVDF膜,恒流300mA转膜60分钟(冰浴),避免小分子蛋白穿透膜。 IF双标实验(肿瘤微环境研究): 推荐与α-SMA抗体共染(肌成纤维细胞标志物),使用Alexa Fluor 488(绿色,标记FSP-1)和594(红色,标记α-SMA),激光共聚焦观察CAF的双阳性表达。 公司正在出售的产品
