| Purity |
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC |
| Endotoxin Level |
Less than 1EU per μg by the LAL method. |
| Biological Activity |
Measured by its binding ability in a functional ELISA. Immobilized CD3E&CD3G [Biotin], His, Human at 2μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml) can bind Anti-CD3 Antibody, mFc Tag. Test result was comparable to standard batch. |
| Expression System |
HEK293 |
| Theoretical Molecular Weight |
17.9 kDa (CD3E) and 17.9 kDa (CD3G) |
| Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 25-40 kDa based on Bis-Tris PAGE result. |
| Formulation |
Lyophilized from a 0.22 μm filtered solution in PBS，(pH 7.4). |
| Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
| Storage & Stability |
Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |

| Target Background |
T-cell surface glycoprotein CD3 epsilon & CD3 gamma chain, also known as CD3E & CD3G , are single-pass type I membrane proteins.When antigen presenting cells (APCs) activate T-cell receptor (TCR), TCR-mediated signals are transmitted across the cell membrane by the CD3 chains CD3D, CD3E, CD3G and CD3Z. All CD3 chains contain immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain. |
| Synonyms |
