Fig. 6From: 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 probesSerotype specificity identification of sdAbs against FMDV serotype O, Asia 1, and A antigens. All samples were tested for absorbance at 450 nm. The negative camel serum was coated as the negative control, and the polyclonal antibodies against FMDV type O were coated as the positive control.
