Optimized DNA sequence  encoding  extracellular domain of Human CD3δ including a C-terminal His tag, were expressed in HEK293 cells.

Molecular weight:

Recombinant CD3δ  is a  protein consisting of Phe22-Ala125 amino acid residue subunits,  due to glycosylation migrates as an approximately 18-25kDa protein on SDS-PAGE.

>95%, as determined by SDS-PAGE and HPLC

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 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 delta

he preT-cell receptor (TCR) and the αβTCR are multimeric protein complexes expressed on the surface of developing T cells at different stages of their ontogeny in the thymus. The pre-TCR complex consists of a disulfide- linked heterodimer of an invariant pre-Tα (pTα) and a variable TCRβ chain noncovalently associated with the CD3γ, δ, ϵ, and ζ polypeptides. The overall structure and functioning of the pre-TCR and TCR complexes in mice and humans are quite similar. Despite this similarity, ablation of the highly related CD3δ and CD3γ subunits has markedly different effects in mice and humans.
