Cat.No.: HA-646V
Product Overview: Recombinant Influenza A virus (A/Zhejiang/1/2013(H7N9)) hemagglutinin (EPI443034) (Met1-Val524) was expressed with a C-terminal polyhistidine tag.
Source: Baculovirus-Insect cells
Species: H7N9
Tag: His
Predicted N Terminal: Asp 19
Form: Lyophilized from sterile 20mM, Tris 500mM NaCl, 10% glycerol, pH 7.4, 5%~8% trehalose and mannitol.
Bio-activity: 1. Measured by its ability to agglutinate guinea pig red blood cells. HA titer is 0.1-0.5 μg/ml for 1% GRBC. It also agglutinates chick red blood cells. 2. Measured by its ability to bind with Neu5Aca2-3Galb1-4GlcNAcb-PAA-biotin (01-077) using the Octet R
Molecular Mass: The recombinant hemagglutinin of Influenza A virus (A/Zhejiang/1/2013(H7N9)) comprises 517 amino acids and has a predicted molecular mass of 57.6 kDa. The apparent molecular mass of the protein is approximately 57-64 kDa in SDS-PAGE under reducing conditions.
Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
Purity: >95 % as determined by SDS-PAGE.
Stability: Samples are stable for up to twelve months from date of receipt at -70ºC.
Storage: Store it under sterile conditions at -20ºC~-70ºC. 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 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
