背景介绍
CD3 is a multimeric protein associated with the T-cell receptor (TCR) to form a complex involved in antigen recognition and signal transduction (PMID: 15885124). CD3 is composed of CD3γ, δ, ε, and ζ chains (PMID: 1826255). It is expressed by thymocytes in a developmentally regulated manner, T cells, and some NK cells (PMID: 3289580). The TCR recognizes antigens bound to major histocompatibility complex (MHC) molecules. TCR-mediated peptide-MHC recognition is transmitted to the CD3 complex, leading to the intracellular signal transduction (PMID: 11985657). This polyclonal antibody was raised against the epsilon chain of rat CD3 molecule.

/CD3复合体所特有，它可以不依赖CD3的其它亚单位而存在于NK中，并同FcζγRⅢ（CD16）相连。此外，在TCR触发后，ζ链可以同一胞浆内称为ζ链相关蛋白70（ZAP-70）相结合，AP-70为一种胞浆内具有PTK活性的信号蛋白，含有两个SH-2（src homology region 2,SH-2）结构域以及一个与猪脾中PTK syk相关的激酶结构域，ZAP-70分子中SH-2与ζ链中磷酸化的酪氨酸残基相结合，ζ链的酷氨酸磷酸化是由p59 fyn 或p56 lck
【摘要】目的 构建和表达抗CD3/抗Pgp微型双功能抗体，并测定该微型双功能抗体的生物学活性。方法 采用PCR和overlap PCR方法构建抗CD3/抗CD20微型双功能抗体，并用双脱氧终止法测定DNA序列；采用亲和层析法纯化该产物，并用Western blot和分子排阻层析鉴定纯化产物；采用免疫荧光法、放射免疫分析法和玫瑰花环试验鉴定纯化产物与靶细胞的结合活性。结果 DNA序列测定结果表明：抗CD3/抗Pgp微型双功能抗体已构建成功，表达可溶性产物的产量达2mg/l以上，纯化产物中二
