Sialic acid binding
WebBridging the gap between genome and pathogenic expression remains a challenge. Using sialic acid as a universal Influenza virus binding receptor, a novel virus avidin-biotin complex-based capture coating was developed and characterized that may be used to create future diagnostic and interrogation platforms for viable whole Influenza virus. WebBy definition, siglecs bind sialic acid, but the story is much more complicated than that, largely because the conformation of the sialic acid, along with other factors such as core protein expression, multivalency, and sulfation all contribute to binding specificity. …
