Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
Protein bands: 10kDa, 14kDa, 18kDa, 22kDa, 26kDa, 33kDa, 44kDa and 70kDa.
Double intensity bands: The 26kDa, 18kDa, 10kDa bands are at double intensity to make location and size approximation of proteins of interest quick and easy.
T-细胞表面糖蛋白CD3ε(CD3ε)重组蛋白Ready-to-use: No need to heat, dilute or add reducing agents before use.

文献和实验Flow Cytometric Detection of Cytoplasmic and Surface CD3-ε Expression in Developing T Cells
8. However, the acquisition of a functional T-cell antigen receptor (TCR)/CD3 complex is perhaps the most significant of the events that take place during early thymocyte development. This multisubunit complex consists of two disulfide-linked variant TCRα/β (or TCRγ/δ) chains
链的结构，包括氨基端104个亲水性氨基酸，穿膜部分为26个氨基酸残基，胞浆内为81个氨基酸残基。编码ε基因与δ链基因连锁在一起。研究表明，ε链胞浆内功能域的缺失不会导致明显的信号转导障碍，且缺乏ε链的TCDR/CD3复合体足以产生抗原介导的细胞活化和IL-2的产生。但通过构建嵌合分子进行基因转染试验证实，在缺失ζ链的淋巴细胞中，ε链胞浆功能域可以转导淋巴细胞活化信号。另外，ε和ζ胞浆功能域活化T细胞可引起不同方式的蛋白磷酸化，提示ε和ζ亚单位可能涉及到两种不同的独立的跨膜信号转导生化途径。目前研究发现
重磅！Science 子刊揭示 T 细胞受体的「秘密生活」及其在免疫反应中的作用
T 细胞抗原受体 (T cell receptor, TCR) 是一种多亚基复合体，通过结合抗原提呈细胞 (APC) 表面的抗原肽 - MHC 分子复合物（pMHC）来特异性识别抗原，对 T 细胞发挥免疫功能至关重要。TCR 可以识别「自我」和「非我」抗原，并根据抗原的特质引发特异性的下游信号通路，从而使得 T 细胞产生特异性分化并获得不同的效应功能。TCR 有 4 种 CD3 信号链（CD3γ/δ/ε/ζ），共携带了 20 个酪氨酸磷酸化位点。不同的抗原刺激会引起不同的 TCR 磷酸化模式
