Recombinant extracellular domain of Influenza A virus (A/chicken/Netherlands/1/03 (H7N7)) (AAR02639.1) hemagglutinin (Met 8-Phe 544) (Native, HA1+HA2) was expressed, fused with a polyhistidine tag at the C-terminus.
Predicted N Terminal:
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
1. Measured in hemagglutination test using 1% chicken erythrocyte. The HA titer is 0.1-0.5 μg/ml for 1% CRBC.2. Measured by its ability to bind with Neu5Aca2-3Galb1-4GlcNAcb-PAA-biotin (01-077) using the Octet RED System.
The secreted recombinant hemagglutinin of Influenza A virus (A/chicken/Netherlands/1/03 (H7N7)) comprises 530 amino acids and has a calculated molecular mass of 59.4 kDa as estimated in SDS-PAGE under reducing conditions.
< 1.0 EU per μg of the protein as determined by the LAL method.
>80 % as determined by SDS-PAGE.
Samples are stable for up to twelve months from date of receipt at -70ºC.
Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
