产品名称 Bcl-2 Recombinant Rabbit mAb 产品介绍
商品属性 产品介绍The Bcl-2 gene was isolated at the chromosomal breakpoint of t(14;18)-bearing follicular B cell lymphomas(1,2).Bcl-2 blocks cell death following a variety of stimuli and confers a death-sparing effect to certain hematopoietic cell lines following growth factor withdrawal (3,5).Bcl-2 appears to function in several subcellular locations yet lacks any known motifs that would confer insight into its mechanism of action (6,7).A more recently identified protein,designated Bax p21(i.e., Bcl-associated X protein ),has extensive amino acid homology with Bcl-2 and both homodimerizes and forms heterodimers with Bcl-2(8). Overexpression of Bax accelerates apoptotic death induced by cytokine deprivation in an IL-3 dependent cell line and Bax also counters the death repressor activty of Bcl-2(8).

PubMedPubMed 靶点与功能 Bcl-2(B-cell lymphoma 2)是抗凋亡蛋白家族核心成员(分子量约26kDa),核心功能与研究价值包括: 凋亡“刹车”机制:通过BH1-4结构域与促凋亡蛋白(Bax/Bak)结合,抑制线粒体膜通透化(MOMP)和细胞色素C释放,在白血病、淋巴瘤中过表达可导致化疗耐药; 肿瘤微环境调控:在肿瘤相关巨噬细胞(TAM)中高表达,通过IL-10/STAT3通路促进免疫抑制,与PD-L1共表达提示不良预后; 神经保护作用:在神经元中表达可抑制氧化应激诱导的凋亡,与阿尔茨海默病(AD)的神经退行性变负相关。 实验操作关键要点 WB凋亡模型验证: 样本处理:5-FU(5μg/mL)诱导Hela细胞凋亡48小时,RIPA裂解液(含1mM PMSF)冰上裂解30分钟,12000g离心15分钟取上清; 电泳条件:12% SDS-PAGE凝胶,恒压80V浓缩胶、120V分离胶,电泳90分钟; 抗体孵育:抗体1:1000稀释(5% NF-Milk+TBST),室温孵育2小时,HRP二抗(1:50000)室温1小时,曝光时间30秒(凋亡组Bcl-2条带灰度值降低50%)。 IHC-P淋巴瘤诊断: 抗原修复:柠檬酸盐缓冲液(pH6.0)微波修复15分钟(石蜡切片),滤泡性淋巴瘤B细胞核/胞质呈棕黄色阳性,正常淋巴结生发中心阴性; 阳性对照:Raji细胞爬片(强阳性); 联合染色:与Ki-67共染,Bcl-2⁺/Ki-67⁺双阳性细胞比例>30%提示高增殖活性。 IF线粒体共定位: 与Tom20(线粒体外膜蛋白) 共染,Bcl-2(绿色)在线粒体(红色)周围呈“点状共定位”,凋亡诱导后共定位系数降低(从0.8降至0.3)。 公司正在出售的产品
