NA/Neuraminidase Protein is a receptor-destroying enzyme that cleaves terminal sialic acids from cellular receptors, potentially facilitating viral invasion of the upper airways by targeting sialic acid moieties on airway epithelial cell mucin. NA plays a pivotal role in viral propagation by catalyzing the removal of terminal sialic acid residues from both viral and cellular glycoconjugates. Moreover, the sialidase activity in late endosome/lysosome traffic appears to enhance virus replication. NA/Neuraminidase Protein, H7N9 (EPI439509, HEK293) is the recombinant Virus-derived NA/Neuraminidase protein, expressed by HEK293 , with tag free. It originates from cell lysates collected after expressing a DNA sequence encoding the Influenza A virus neuraminidase.
