BioXCell--RecombiMAb anti-mouse PD-L1 (B7-H1) (D265A)
产品描述：
10F.9G2™-CP001单克隆抗体是原始10F.9G2™单克隆抗体的重组嵌合型抗体。可变结构域序列与原始10F.9G2™克隆号相同，但是恒定区序列已经从大鼠IgG2b变为小鼠IgG1。10F.9G2™-CP001单克隆抗体在Fc片段中也含有D265A突变，使其无法与内源性Fcγ受体结合。
10F.9G2™-CP001单克隆抗体与小鼠PD-L1（程序性死亡配体1，也称为B7-H1或CD274）反应。PD-L1是属于Ig超家族的B7家族的I型跨膜蛋白，分子量为40kDa。PD-L1在T淋巴细胞、B淋巴细胞、NK细胞、树突状细胞以及IFNγ刺激的单核细胞、上皮细胞和内皮细胞上表达。PD-L1与CD4和CD8胸腺细胞以及活化的T和B淋巴细胞和骨髓细胞上的受体PD-1结合。PD-L1与PD-1的结合导致抑制TCR介导的T细胞增殖和细胞因子产生。PD-L1被认为在肿瘤免疫逃逸中起着重要作用。诱导的PD-L1表达在许多肿瘤中很常见，并导致肿瘤细胞对CD8+ T细胞介导的裂解的抗性增加。在黑色素瘤的小鼠模型中，可以通过用阻断PD-L1和PD-1之间相互作用的抗体进行治疗，暂时抑制肿瘤生长。10F.9G2™单克隆抗体已被证明可以阻断PD-L1和PD-1之间以及PD-L1和B7-1之间的相互作用（CD80）。
