产品详情介绍
CD45是一种180-240 kDa的单链 I 型跨膜糖蛋白[1],又称Protein tyrosine phosphatase, receptor type C(PTPRC),或T200 glycoprotein、T200 leukocyte common antigen 等,在除红细胞或血小板外的所有造血细胞的质膜上均有表达[2]。CD45结构包括一个胞外结构域、一个跨膜区和两个串联胞内催化结构域。CD45是protein tyrosine phosphatase(PTP)家族成员,能够调节细胞生长、分化、细胞周期和癌基因转化等多种细胞过程[3]。另外,CD45还在T细胞和B细胞抗原受体介导的去磷酸化底物(包括p56lck、p59fyn和其他src家族激酶)激活中起着关键作用[4]。本产品为小鼠抗人CD45单克隆抗体,用于WB、IF和FC方法特异性检测人CD45蛋白。
