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. Specifications Synonyms CD3; CD3e; CD3E; CD3d; T3D; CD3D; CD3E&CD3D; CD3 delta&CD3 epsilon Uniprot No. P07766(CD3E)&P04234(CD3D) Source Recombinant Human CD3E&CD3D/CD3 epsilon&CD3 delta Protein is expressed from HEK293 Cells with hFc at the C-terminal. It contains Asp23 - Asp126 (CD3E) & Phe22 - Ala105(CD3D). Molecular Weight Approximately 37.8 kDa (CD3E) and 35.4 kDa (CD3D). Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result. Purity > 95% as determined by SDS-PAGE and HPLC. Activity ELISA Data: Immobilized Human CD3E&CD3D, hFc Tag at 0.5μg/ml (100μl/Well). Dose response curve for Biotinylated Anti-CD3E&CD3D Ab.1, hFc Tag with the EC50 of 31.68ng/ml determined by ELISA. ELISA Data: Immobilized Human CD3E&CD3D, hFc Tag at 0.1μg/ml (100ul/Well). Dose response curve for Anti-CD3E&CD3D Ab.2, mFc Tag with the EC50 of 27.0ng/ml determined by ELISA. Endotoxin < 1.0 EU per 1μg of the protein by the LAL method. Formulation Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. 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. Storage Transported with ice packs. Store at -20℃ to -80℃, valid for one year. After reconstitution, store at -20 to -80°C in unopened state for 3-6 months. After reconstitution, store at 2-8°C for 2-7 days. It is recommended to store in aliquots and freeze for the first use to avoid repeated freezing and thawing. Note 1. Avoid repeated freezing and thawing. 2. For your safety and health, please wear a lab coat and disposable gloves when operating. 3.This product is for research use only.
