Species : |
H1N1 |
Source : |
HEK293 |
Tag : |
His |
Protein Length : |
1-344 a.a. |
Form : |
Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. |
Molecular 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. |
Endotoxin : |
< 1.0 EU per μg of the protein as determined by the LAL method |
Purity : |
> 97 % as determined by SDS-PAGE |
Storage : |
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
Reconstitution : |
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents. |
