Recombinant Human CD3E&CD3D/CD3 epsilon & CD3 delta (His Tag) | 93341ES60 | 100 μg |
93341ES76 | 500 μg | |
93341ES80 | 1 mg |
產品描述
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.
產品性質
別名（Synonyms） | CD3; CD3e; CD3E; CD3d; T3D; CD3D; CD3E&CD3D; CD3 delta&CD3 epsilon |
Uniprot No. | P07766(CD3E)&P04234(CD3D) |
表達區間及表達系統（Source） | Recombinant Human CD3E&CD3D/CD3 epsilon&CD3 delta Protein is expressed from HEK293 Cells with His tag at the C-terminal. It contains Asp23-Glu120 (CD3E)&Phe22-Ala105 (CD3D). |
分子量(Molecular Weight) | The protein has a predicted MW of 17.9 kDa (CD3E) and 16.7 kDa (CD3D). Due to glycosylation, the protein migrates to 18-25 kDa based on Tris-Bis PAGE result. |
外觀(Physical Appearance） | Sterile Filtered White lyophilized (freeze-dried) powder. |
純度（Purity） | > 95% as determined by SDS-PAGE and HPLC |
活性（Activity） | 1.ELISA Data：Immobilized Human CD3E&CD3D at 2μg/ml (100μl/Well) on the plate. Dose response curve for OKT3, mFc Tag with the EC50 of 38ng/ml determined by ELISA. 2.ELISA Data：Immobilized Human CD3E&CD3D at 2ug/ml (100μl/Well). Dose response curve for Foralumab, hFc Tag with the EC50 of 18.5ng/ml determined by ELISA. |
內毒素（Endotoxin） | < 1.0 EU per 1μg of the protein by the LAL method. |
制劑（Formulation） | Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
復溶（Reconstitution） | Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
