分子别名（Synonym）:HA

种属（Species）：H5N1

表达系统（Expressed Host）：HEK293 Cells

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4

分子量（Molecule Mass）：The secreted recombinant hemagglutinin of Influenza A virus H5N1 (A/bar-headed goose/Qinghai/14/2008) comprises 522 amino acids with the predicted molecular mass of 59.5 kDa. As a result of glycosylation, it migrates as an approximately 70 kDa band in Non-reduced SDS-PAGE and also exists as polymers.

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 extracellular domain of Influenza A virus (A/bar-headed goose/Qinghai/14/2008 (H5N1)) (ACL28277.1) HA (Ser 2-Gln 531) with cleavage site mutated (RERRRKKR → TETR, HA1+HA2, uncleaved) 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.
