Product overview
Recombinant Mouse CD3E&CD3D/CD3 epsilon&CD3 delta Protein is expressed in HEK293 cells with an hFc (IgG1) tag at the C-terminus of CD3E and CD3D. It contains amino acid residues Asp23-Asp108(CD3E) and Phe22-Ala105(CD3D) (accession: P22646(CD3E) & P04235(CD3D)).
Product Details
- Molecular Aliases
- CD3; CD3e; CD3E; CD3d; T3D; CD3D; CD3E&CD3D; CD3 delta&CD3 epsilon
- Protein Length
- Asp23-Asp108
- Expression System
- HEK293
- Theoretical Molecular Weight
- The protein has a predicted MW of 36.1 kDa (CD3E) and 35.2 kDa (CD3D). Due to glycosylation,the protein migrates to 50-65 kDa and 40-50 kDa based on Bis-Tris PAGE result.
- Purity
- > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
- Endotoxin
- Less than 1 EU per μg by the LAL method.
- Buffer / Formulation
- Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
- State
- Lyophilized
- Storage Conditions
- -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
- Reconstitution Advice
- Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

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.
