Recombinant mouse antibody (ADD056) is capable of binding to Methotrexate. The anti-methotrexate antibody features a remarkably rigid tunnel-like binding site that extends into a water channel serving as a specialized route to move solvent out and into the site upon ligand binding and dissociation.
Figure 1 Thermodynamic equilibrium of methotrexate-fluorescein:- Fab of mAb ADD056.
(a) Equilibrium titration of Fab into 50 pM methotrexate-fluorescein at ambient temperature. Measured values (symbols) fit to the model described by eq 2 (line) with a dissociation constant KD of ∼3.6 pM. (b) Van't Hoff plot for association constants KA. Energies were calculated from its linear regression, according to eq 5.
