Structural and computational analyses show that CR8020 binds HA residues subject to antigenic drift and host selection pressure, with escape mutations observed in some H7N9 strains. Additionally, effective engagement of Fcγ receptors (FcγR) is crucial for antibody efficacy, but membrane steric hindrance may limit HA-CR8020-FcγR complex formation. These findings highlight epitope mutability and immune complex accessibility as key factors in bNAb development.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHost species\u003c\/b\u003e:Human\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTested applications\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSpecies reactivity\u003c\/b\u003e:Influenza A virus (strain A\/Hong Kong\/1\/1968 H3N2)\u003c\/p\u003e\u003cp\u003e\u003cb\u003eForm\u003c\/b\u003e:Liquid\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStorage buffer\u003c\/b\u003e:0.01M PBS, pH 7.4.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e:\u0026gt;95% purity as determined by SDS-PAGE.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eClonality\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eIsotype\u003c\/b\u003e:IgG1-lambda\u003c\/p\u003e\u003cp\u003e\u003cb\u003eApplications\u003c\/b\u003e:ELISA, Bioactivity: FACS, Functional assay, Research in vivo\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTarget\u003c\/b\u003e:Hemagglutinin, Hemagglutinin HA1 chain, Hemagglutinin HA2 chain, HA\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurification\u003c\/b\u003e:Protein A\/G purified from cell culture supernatant.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEndotoxin level\u003c\/b\u003e:Please contact us for this information.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eExpression system\u003c\/b\u003e:Mammalian Cells\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAccession\u003c\/b\u003e:Q91MA7\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStability and Storage\u003c\/b\u003e:Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
