  • Patent number: 11980669
    Abstract: An antibody production process in mammalian cells in which engineered unpaired cysteine residues are post-translationally modified and capped with particular chemical entities, which capped antibodies are well suited to further site-specific conjugation steps to form antibody-drug conjugates (ADCs) or protein drug conjugates; ADCs produced using these capped antibodies including in particular ADCs formed by the selective reduction of the capped antibodies' cysteine residues, and ADCs formed using chemical handles such as aldehyde/azide/alkyne biorthogonal groups, which permit additional drug conjugation chemistry; and uncapped antibodies produced by cells in low cysteine, cysteine and glutathione media, and ADCs produced via direct conjugation to these uncapped antibodies.
