Fig. 2From: 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 probesMonoclonal phage ELISA. A total of 131 random clones from the sdAb library were analyzed with monoclonal phage ELISA. FMDV type O antigens at 10 μg/mL were coated in each well. PBS was used as the negative control. A total of 12 clones were selected on the basis of absorbance. The x-axis presents the clone number, and the y-axis shows the absorbance values at 450 nmBack to article page
