---|---|
Species | Human |
Sequence | Asp23-Asp126 (CD3E)&Phe22-Ala105 (CD3D) |
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&CD3D [Biotin], His, Human at 0.5 µg/ml (100 µl/well) on the streptavidin precoated plate (5 µg/ml) can bind OKT3, mFc Tag. Test result was comparable to standard batch. |
Expression System | HEK293 |
Theoretical Molecular Weight | 17.9 kDa (CD3E) and 16.7 kDa (CD3D) |
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 delta chain, also known as CD3E&CD3D, 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. |
