HA1-348I |
| Product Overview : |
Recombinant Influenza A H9N2 (A/Guinea fowl/Hong Kong/WF10/99) HA1 Protein, His & Avi-tagged, Biotinylated is expressed from human 293 cells (HEK293). It contains AA Asp 19 - Arg 338 (Accession # Q80KD9-1). Predicted N-terminus: Asp 19. This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag. The protein has a calculated MW of 39.3 kDa. The protein migrates as 47-70 kDa under reducing (R) condition (SDS-PAGE). The biotin to protein ratio is 0.5-1 as determined by the HABA assay. |
