(18) Brief digestion at neutral pH without reduction produced a molecule in which the Fab and Fc fragments were still linked by a pair of labile disulphide bridges, and the Fc fragment released by cleaving these bonds, called 1Fc fragment, contained a portion of the ;hinge' region including an interchain disulphide bridge.
(19) Both adiphenine.HCl and proadifen.HCl form more stable complexes, suggesting that hydrogen bonding to the carbonyl oxygen by the hydroxyl-group on the rim of the CD ring could be an important contributor to the complexation.
(20) However, peptide bonds between 193 and 194, and 194 and 195 were cleaved in the presence of mAb 1C3 as easily as in the presence of mAb 31A4, suggesting that the region of residues 200 to 202 was obscured by, or within the antibody binding site, but that the region of residues 193 to 195 was not.
