产品名称 CD5 Recombinant Rabbit mAb 产品介绍
商品属性 产品介绍This gene encodes a member of the scavenger receptor cysteine-rich (SRCR) superfamily. Members of this family are secreted or membrane-anchored proteins mainly found in cells associated with the immune system. This protein is a type-I transmembrane glycoprotein found on the surface of thymocytes, T lymphocytes and a subset of B lymphocytes. The encoded protein contains three SRCR domains and may act as a receptor to regulate T-cell proliferation. Alternative splicing results in multiple transcript variants encoding different isoforms.

PubMedPubMed 靶点与功能 CD5是跨膜糖蛋白,主要表达于95%胸腺细胞、成熟T细胞及B-1a B细胞亚群(约5%外周B细胞),通过调控TCR/BCR信号通路阈值参与免疫耐受和自身免疫反应。其异常表达与T细胞淋巴瘤(如套细胞淋巴瘤CD5⁺)、慢性淋巴细胞白血病(CLL) 密切相关,是淋巴瘤病理诊断的重要标志物(例如区分套细胞淋巴瘤与滤泡中心淋巴瘤,后者CD5⁻)。 实验操作关键要点 WB实验(Jurkat T细胞裂解液): 样本处理:使用含1mM PMSF的RIPA裂解液冰上裂解20分钟,12000g离心15分钟取上清,上样量推荐30-50μg; 电泳条件:10% SDS-PAGE凝胶,恒压80V浓缩胶、120V分离胶,转膜采用0.45μm PVDF膜(250mA恒流60分钟); 抗体孵育:一抗1:2000稀释(5%脱脂奶粉+TBST),4℃孵育过夜,HRP二抗(山羊抗兔)1:5000室温孵育1小时,曝光时间15-30秒(预期条带67kDa)。 流式细胞术(外周血T细胞检测): 样本制备:EDTA抗凝血经红细胞裂解液处理后,PBS洗涤2次,调整细胞浓度至1×10⁶/mL; 染色步骤:FITC标记CD5抗体(1:50稀释)避光孵育20分钟(4℃),无需洗涤直接上样(避免荧光淬灭); 设门策略:先通过FSC/SSC设门淋巴细胞群,再以CD5⁺CD3⁺双阳性定义T细胞亚群(正常外周血T细胞CD5阳性率>90%)。 IHC-P(淋巴瘤组织切片): 抗原修复:柠檬酸钠缓冲液(pH6.0)微波修复15分钟(95℃),自然冷却; 阳性定位:T细胞胞膜呈棕黄色线性着色,套细胞淋巴瘤可见肿瘤细胞弥漫性膜阳性,而滤泡性淋巴瘤阴性; 对照设置:以正常扁桃体组织为阳性对照(T细胞区棕黄色膜染色),胃癌组织为阴性对照(上皮细胞无着色)。 公司正在出售的产品
