InVivoMAb anti-rat/mouse CD71 (TfR1)
Useful for targeted drug delivery to the brain
研发背景:
OX-26单克隆抗体可识别大鼠的CD71蛋白,CD71蛋白也被称为转铁蛋白受体蛋白1(TfR1)。据报道,该抗体OX-26也与小鼠CD71发生交叉反应。CD71是一种170-180kda的II型同型二聚体跨膜糖蛋白,其表达于增殖细胞、网状细胞和类红细胞前体等细胞的表面。
CD71在调节细胞增殖中起着重要作用,它是通过细胞内吞作用将铁从转铁蛋白转运到细胞内的。有研究表明,CD71在恶性肿瘤细胞中高水平表达,其表达与肿瘤的进展有关。这种在恶性细胞上的高表达,加上CD71的内化能力以及铁对癌细胞增殖的必要性,会使转铁蛋白受体成为一个有吸引力的靶点,可用于将药物输送到恶性细胞。OX-26与CD71的胞外结构域结合后,通过内源性转铁蛋白转运系统进入血脑屏障(Blood-Brain Barrier,BBB)。在这一机制下,OX-26抗体常被用于在实验性大鼠模型中通过BBB转运结合药物。
