HA Protein (C-His, H7N9)

1. Measured by its ability to agglutinate guinea pig red blood cells. HA titer is 0.06-0.6μg/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 RED System. 3. Measured by its ability to bind with Neu5Aca2-6GalNAca-PAA-biotin (01-059) using the Octet RED System.

The recombinant hemagglutinin of Influenza A virus (A/Hangzhou/3/2013 (H7N9) ) comprises 517 amino acids and has a predicted molecular mass of 57.6 kDa. The apparent molecular mass of the protein is approximately 58 kDa in SDS-PAGE under reducing conditions.
