Figure 1From: Combining magnetic nanoparticle with biotinylated nanobodies for rapid and sensitive detection of influenza H3N2The whole procedure. Schematic representation of the strategy to select the influenza A grade 2 (H3N2)-specific single-domain antibodies and to apply the detection approach. The H3N2-specific VHH genes were cloned and selected from an immunized dromedary. Nanobodies identified to recognize different epitopes were used to couple with biotin or HRP to detect antigen.Back to article page
