The present invention relates to antibodies and antibody fragments, one or more of whose native inter-chain disulfide bridges have been replaced with a specific bridging moiety. The bridging moiety can be selectively targeted to inter-chain disulfide bonds within the antibody or antibody fragment, enabling the construction of more homogenously modified products such as antibody-drug conjugates.
