分子别名（Synonym）:HA
 

种属（Species）：H1N1
 

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 HA1 subunit of H1N1 HA (A/California/04/2009 (H1N1)) comprises 338 amino acids with the predicted molecular mass of 38 kDa. As a result of glycosylation, it migrates as an approximately 50-60 kDa band 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 an N-terminal segment (Ser 2-Arg 344) of Influenza A H1N1 hemagglutinin (A/California/04/2009 (H1N1)) (ACP41105.1), termed as HA1, was fused 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.
