This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.A recombinant form of the H7 hemagglutinin (HA) protein from influenza A virus, A/Anhui/1/2013 (H7N9) containing a C-terminal histidine tag was produced in Sf9 insect cells using a baculovirus expression vector system and purified by nickel affinity chromatography. The predicted transmembrane and endodomain coding regions of the HA gene were replaced with a synthetic gene segment encoding a thrombin cleavage site, trimerizing (foldon) domain and six histidine residues, as described for several influenza A virus subtypes. The full-length HA precursor protein is 560 residues (GISAID EpiFlu: EPI439507).Each vial contains 100 ?g to 200 ?g of purified recombinant HA protein in PBS (pH 7.4) with 50% glycerol.
