CD4（CD4 molecule） encodes a membrane glycoprotein of T lymphocytes that interacts with major histocompatibility complex class II antigenes and is also a receptor for the human immunodeficiency virus. CD4 is expressed not only in T lymphocytes, but also in B cells, macrophages, and granulocytes. It is also expressed in specific regions of the brain. The protein functions to initiate or augment the early phase of T-cell activation, and may function as an important mediator of indirect neuronal damage in infectious and immune-mediated diseases of the central nervous system. Multiple alternatively spliced transcript variants encoding different isoforms have been identified in CD4.蛋白别名为：CD4; T-cell surface glycoprotein CD4; T-cell surface antigen T4/Leu-3; CD antigen CD4;基因ID为：920；蛋白质ID:P01730
应用类型
IHC-p，IF，ELISA补充：最优的抗体稀释比例需要基于客户实验进行优化.建议的起始稀释比例如下: IHC-p: 1:100-1:300, IF: 1:200-1:1000, ELISA: 1:40000. Not yet tested in other applications.
免疫原
