CD3E Protein Product Information
A DNA sequence encoding the human CD3E ( Met 1-Asp126) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
|Expression Host:||Human Cells|
CD3E Protein QC Testing
|Purity:||(84.6+ 14.1) % as determined by SDS-PAGE||SDS-PAGE:
|Endotoxin:||< 1.0 EU per μg of the protein as determined by the LAL method|
|Stability:||Samples are stable for up to twelve months from date of receipt at -70℃|
|Predicted N terminal:||Gln 22|
The secreted recombinant human CD3E is a disulfide-linked homodimeric protein. The reduced monomer comprises 355 amino acids and has a predicted molecular mass of 40 kDa. As a result of glycosylation, it migrates as an approximately 44-53 and 38 kDa band in SDS-PAGE under reducing conditions.
|Formulation:||Lyophilized from sterile PBS, pH 7.4.
CD3E Protein Usage Guide
|Storage:||Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.|
|Reconstitution:||A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.|

CD3E Protein Description
T-cell surface glycoprotein CD3 epsilon chain, also known as CD3E, is a single-pass type I membrane protein. CD3E contains 1 Ig-like (immunoglobulin-like) domain and 1 ITAM domain. CD3E, together with CD3-gamma, CD3-delta and CD3-zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T cell receptor-CD3 complex. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. T cell receptor-CD3 complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. This complex is critical for T-cell development and function, and represents one of the most complex transmembrane receptors. The T cell receptor-CD3 complex is unique in having ten cytoplasmic immunoreceptor tyrosine-based activation motifs (ITAMs). CD3E plays an essential role in T-cell development, and defects in CD3E gene cause severe immunodeficiency. This gene has also been linked to a susceptibility to type I diabetes in women. CD3E has been shown to interact with TOP2B, CD3EAP and NCK2.
