Optimized DNA sequence encoding Human extracellular domain of human CD16bincluding a C-terminal 6His tag was expressed in HEK293 cells.
Recombinant CD16b is a monomer protein consisting of 195 amino acid residue subunits, due to glycosylation migrates as an approximately50 kDa 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 CD16b is supplied as a lyophilized 0.2 μm filtered PBS solution, pH7.4 containing 5% trehalose.
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL.
Recombinant CD16b, as supplied, can be stored in working aliquots at 2° - 8° C for one month, or at -20° to-70°C for twelve months. Avoid repeated freeze/thaw cycles.
