重组抗小鼠CD3单克隆抗体(克隆号17A2) ，大鼠IgG2b Kappa（Recombinant Anti-mouse CD3 Monoclonal Antibody (Clone: 17A2), Rat IgG2b Kappa，货号：PA007254.r2b Syd Labs）

抗小鼠CD3单抗（又称17A2抗体）是一种特异性识别小鼠T细胞受体（TCR）复合体中CD3ε链的单克隆抗体。CD3分子与TCR非共价结合，在T细胞抗原识别及信号转导过程中发挥核心调控作用，主要表达于成熟T细胞及胸腺细胞表面。在现代免疫学研究中，17A2抗体被广泛应用于流式细胞术中T细胞亚群的精准检测、免疫表型分析，以及在体内实验中用于T细胞激活、刺激或特定免疫调节干预。通过结合并交联TCR-CD3复合体，抗小鼠CD3单抗能够有效模拟抗原刺激，诱导T细胞增殖与活化，是研究细胞免疫应答机制、自身免疫性疾病模型及肿瘤免疫学不可或缺的重要工具。

作为专业的生命科学试剂供应商，Syd Labs推出的重组抗小鼠CD3单抗（克隆号17A2）采用高效的哺乳动物细胞表达系统进行重组生产，确保了产品高纯度与卓越的批次一致性。该产品属大鼠IgG2b Kappa同型格式，完全达到严格的体内实验级标准，具备超低的内毒素水平，能够有效避免非特异性刺激与细胞毒性干扰。无论是用于流式细胞术多色分析还是开展高要求的体内功能实验与免疫干预研究，Syd Labs重组17A2抗体都能为您提供高特异性与可靠的实验数据支持。
