| Description : |
T-cell surface glycoprotein CD3 delta & CD3 gamma chain, also known as CD3D & CD3G or CD3D&CD3G respectively, are single-pass type I membrane proteins. CD3D, together with CD3- epsilon(CD3E) , CD3-gamma and CD3-zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T cell receptor-CD3 complex. T cell receptor-CD3 complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. |

| Tag : |
His & Fc & Flag |
| Predicted N Terminal : |
Asp 23 (CD3E) & Gln 23 (CD3G) |
| Form : |
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4, 10% trehalose. |
| Bio-activity : |
Immobilized Anti-CD3E & CD3G MAb, Mouse IgG2a at 10μg/mL (100 μL/well) can bind Human CD3E & CD3G with a linear range of 0.3-5 μg/mL. |
| Molecular Mass : |
The heterodimer Human CD3 epsilon & CD3 gamma is produced by co-expression of CD3E and CD3G, has a calculated MW of 39.2 kDa (CD3E) and 38.6 kDa (CD3D). Subunit CD3E is fused with a human IgG1 Fc tag at the C-terminus, followed by a polyhistidine tag, and subunit CD3G is fused with a human IgG1 Fc tag at the C-terminus, followed by a Flag tag. The reducing (R) heterodimer protein migrates as 40-50 kDa due to glycosylation. |
| Protein length : |
Asp 23 - Asp 126 (CD3E) & Gln 23 - Ser 116 (CD3G) |
| Endotoxin : |
Less than 1.0 EU per μg by the LAL method. |
| Purity : |
>95% as determined by SDS-PAGE. |
| Storage : |
For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at: 4-8°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution. |
| Storage buffer : |
PBS, pH7.4 |
| Reconstitution : |
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents. |
