Optimized DNA sequence encoding extracellular domain of Mouse CD33 including an IgG1 Fc C-terminal His tag was expressed in HEK293 cells.
Recombinant CD33 (Siglec-3) is a Homodimer protein consisting of two 460 amino acid residue subunits, due to glycosylation migrates as an approximately 60kDa protein on reduced SDS-PAGE.
>90%, 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 Mouse CD33 is lyophilized from 0.2 μm filtered PBS solution, pH7.2 , 5% Trehalose.
Recombinant CD33 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.
