|A DNA sequence encoding the extracellular domain (Met1-Gln539) of the influenza hemagglutinin (A/Duck/Hong Kong/p46/97 (H5N1)) (AAF02306.1) (HA1+HA2, uncleaved), cleavage site mutated (RRRKKR-TETR) was fused with a polyhistidine tag at the C-terminus.|
|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.
|> 92 % as determined by SDS-PAGE|
|< 1.0 EU per μg of the protein as determined by the LAL method|
|Samples are stable for up to twelve months from date of receipt at -70℃|
|The secreted recombinant influenza A H5N1 HA (A/Duck/Hong Kong/p46/97 (H5N1)) comprises 526 amino acids and has a predicted molecular mass of 60 kDa. It migrates as an approximately 65 kDa band in SDS-PAGE under reducing conditions.|
|Lyophilized from sterile PBS, 750mM NaCl, pH 7.4|
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
|Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.|
|A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.|
