NA (neuraminidase) proteins play a key role in viral transmission by catalyzing the removal of terminal sialic acid residues from viral and cellular glycoconjugates. NA plays a role in determining host range, limiting replication, and virulence. NA is associated with the development and progression of type 2 diabetes mellitus (T2D) . NA/Neuraminidase Protein, H1N1 (AYV62750, HEK293, His) is the recombinant Virus-derived NA/Neuraminidase protein, expressed by HEK293 , with N-His labeled tag.
