HEK293 Cells

Species

H1N1

Predicted N Terminal

Asp 18

Molecule Mass

The secreted recombinant hemagglutinin of Influenza A virus (A/California/04/2009 (H1N1)) comprises 523 amino acids with the predicted molecular mass of 59 kDa. As a result of glycosylation, it migrates as an approximately 66-95 kDa band in SDS-PAGE under reducing conditions.

Formulation

Lyophilized from sterile PBS, pH 7.4
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.

Please refer to the specific buffer information in the hard copy of CoA.

Shipping

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.

Stability & Storage

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
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.
