Influenza A H8N4 (A/pintail duck/Alberta/114/1979) Hemagglutinin / HA Protein (His Tag)

HA

Catalog Number P11722-V08H
Organism Species H8N4
Host Human Cells
Synonyms HA
Molecular Weight The secreted recombinant influenza A H8N4 HA (A/pintail duck/Alberta/114/1979 (H8N4)) comprises 523 amino acids and has a predicted molecular mass of 59.6 kDa. As a result of glycosylation, it migrates as an approximately 70-80 kDa band in SDS-PAGE under reducing conditions.
predicted N Asp 18
SDS-PAGE
Purity > 97 % as determined by SDS-PAGE
Protein Construction A DNA sequence encoding the extracellular domain (Met 1-Lys 529) of the influenza A hemagglutinin (A/pintail duck/Alberta/114/1979 (H8N4)) (ABB87729.1) (HA1+HA2, uncleaved) was expressed, fused with a C-terminal polyhistidine tag.
