Cynomolgus CD3E&CD3G Heterodimer Protein, His Tag&Tag Free (MALS verified)
分子别名（Synonym）
CD3 epsilon & CD3 gamma, CD3E & CD3G
表达区间及表达系统（Source）
Cynomolgus CD3E&CD3G Heterodimer Protein, His Tag&Tag Free (CDG-C52W6) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - Asp 117 (CD3E) & Gln 23 - Thr 113 (CD3G) (Accession # Q95LI5-1 (CD3E) & Q95LI7-1 (CD3G)).
Predicted N-terminus: Gln 22 (CD3E) & Gln 23 (CD3G)
蛋白结构（Molecular Characterization）
Cynomolgus CD3E&CD3G Heterodimer Protein, His Tag&Tag Free is produced by co-expression of CD3E and CD3G, has a calculated MW of 16.0 kDa (CD3E) and 14.4 kDa (CD3G). Subunit CD3E is fused with a polyhistidine tag at the C-terminus and subunit CD3G contains no tag at the C-terminus. As a result of glycosylation, the protein migrates as 17-22 kDa under reducing (R) condition, and 33-38 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE).
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度（Purity）
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
T细胞表面糖蛋白CD3 δ链与CD3 γ链（分别简称为CD3D与CD3G）均属于I型单次跨膜蛋白。CD3δ链与CD3ε链、CD3γ链、CD3ζ链以及T细胞受体α/β、γ/δ异源二聚体共同构成T细胞受体-CD3复合物。该复合物在将抗原识别信号与多种细胞内信号转导通路相偶联的过程中发挥关键作用。
