Fig. 7From: Characterization of single-domain antibodies against Foot and Mouth Disease Virus (FMDV) serotype O from a camelid and imaging of FMDV in baby hamster kidney-21 cells with single-domain antibody-quantum dots probesSubcellular localization of FMDV with the sdAb-QD probes. The BHK-21 cells were harvested at 4 h.p.i and processed for immunofluorescence with sdAb-AF488 (green A1 and B1) and sdAb-QDs (red A2 and B2). All nuclei (A3, B3) were stained with DAPI. The merged images show the co-localization of FMDV with different probes. Magnification is 100×Back to article page
