Fig. 1From: Specific detection of foot-and-mouth disease serotype Asia 1 virus by carboxyl-magnetic beads conjugated with single-domain antibodyPrinciple for FMD Asia 1 virus detection using sdAb based on immunomagnetic separation. Carboxyl-adembead are functionalized with anti- FMDV Asia 1 sdAb forming the immunomagnetic beads, and used to capture FMDV Asia 1 in solution. The complexes of beads-sdAb-virus are easily separated from solution using an ordinary magnet. The isolated complexes may be detected by the antigen in both an ELISA and RT-PCR, and can also be utilized in virus isolation and for purifying virusBack to article page
