Influenza A H7N9 (A/Shanghai/1

分子别名（Synonym）:HA 种属（Species）：H7N9 表达系统（Expressed Host）：HEK293 Cells 制剂（Buffer）：Lyophilized from sterile PBS, pH 7.4. 分子量（Molecule Mass）：The recombinant hemagglutinin of Influenza A virus (A/Shanghai/1/2013 (H7N9)) comprises 517 amino acids and has a predicted molecular mass of 57.7 kDa. The apparent molecular mass of the protein is approximately 67, 43 and 30 kDa in SDS-PAGE under reducing conditions. 内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method. 生物活性(Activity)： 表达区间（Protein Construction）：A DNA sequence encoding the Influenza A virus (A/Shanghai/1/2013(H7N9)) hemagglutinin (Ser2-Val524) (cleavage between Arg339 and Gly440, HA1+HA2) was expressed with a C-terminal polyhistidine tag. 存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution. 运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
