The data from these assays were complemented by a glycan array analysis which determined that AAV1 efficiently binds to NeuAcα2-3GalNAcβ1-4GlcNAc as well as glycoproteins containing NeuAcα2-3/α2-6Galβ1-4GlcNAc N-linked glycans. Sialic acids are typically found as terminal monosaccharides of glycans carried by cell surface glycoproteins. Mucin competition was carried out by pretreating rAAV with bovine submandibular gland […]
