Catalog no. :  RKK07766


Optimized DNA sequence  encoding  extracellular domain of Human CD3ε including a flag tag was co-expressed  with a DNA sequence encoding the extracellular domain of CD3δ including a C-terminal His tag, were expressed in HEK293 cells.

Molecular weight:

Recombinant CD3 ε- CD3δ  is a  heterodimer protein consisting of 270 amino acid residue subunits,  due to glycosylation migrates as an approximately 20kDa and as  26kDa bands on reduced SDS-PAGE.

>97%, as determined by SDS-PAGE and HPLC

Biological Activity:
The activity was tested by the ability of immobilized recombinant human CD3 epsilon-CD3 delta heterodimer to bind Human OKT3  with a linear range of 5-20 ng/ml

Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant Human CD3ε-CD3δ  is lyophilized from 0.2 μm filtered PBS solution,  pH7.2 ,  5% Trehalose.

Recombinant CD3 heterodimer can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.

Avoid repeated freeze/thaw cycles.

CD3 epsilon delta

nvariant CD3 subunit dimers (CD3εγ, CD3εδ, and CD3ζζ) are the signaling components of the αβ T cell receptor (TCR). Although CD3γ and CD3δ each dimerize with CD3ε, there are differential CD3 subunit requirements for receptor assembly and signaling among T lineage subpopulations, presumably mandated by structural differences. Although the CD3γ and the CD3δ subunits each pair with CD3ε, there are differences in CD3 subunit requirements for various T lineage populations and their developmental stages.
