Fig. 4From: 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 probesSDS–PAGE analysis of the expression and purification of sdAbs. a Expression of sdAbs in E. coli. Lanes 1 and 2, bacterial lysates from the sdAb-c1 and sdAb-c2 groups under non-inducing conditions. Lanes 3 and 4, bacterial lysates from the sdAb-c1 and sdAb-c2 groups under inducing conditions. (b) Purification of recombinant sdAbs protein. Lanes 1 and 2, purified sdAb-c1 and sdAb-c2. M = molecular weight markers, size indicated in kilodalton (kDa)Back to article page
