Protein Construction: A DNA sequence encoding the human coronavirus (HCoV-OC43) hemagglutinin esterase protein (APU51943.1) (Leu17-Pro394) was expressed with a polyhistidine tag at the C-terminus.
Accession: APU51943.1
Expressed Host: HEK293 Cells
Endotoxin: < 1.0 EU per ?g protein as determined by the LAL method.
Stability and Storage: Lyophilized proteins are stable for up to 12 months when stored at -20 to -80?C. Reconstituted protein solution can be stored at 4-8? for 2-7 days. Aliquots of reconstituted samples are stable at < -20? for 3 months.Lyophilized from sterile PBS, pH 7.4
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
