Optimized DNA sequence encoding extracellular domain of Human CD3ε including a C-terminal His tag was expressed in HEK293 cells. CD3ε was further labled by Biotin for detection by avidin conjugated secondary probes.
Recombinant CD3ε is a protein consisting of116 amino acid residue subunits, due to glycosylation migrates as an approximately 20kDa protein on SDS-PAGE.
>97%, as determined by SDS-PAGE and HPLC
ELISA,WB BiotinylatedCD3ε was designed to be used in single step detection in ELISA ,WB
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 is lyophilized from 0.2 μm filtered PBS solution, pH7.2 , 5% Trehalose.
Recombinant CD3e can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to-70°Cfor twelve months. Avoid repeated freeze/thaw cycles.
