Preferred antibodies include a mutation at light chain position 180 (positional numbering), most preferably the mutation is to a residue selected from C, K, Q, or a non-natural amino acid. Additional mutations may also be combined with a mutation at position 180; including one or more of light chain (LC) S208, LC S171, LC S182, LC A184, LC V191, LC S202, LC S203, LC T206, heavy chain (HC) S160, HC T190, HC S443, HC S447, HC S139, HC S168, HC V170, HC V176, HC T200, HC S445 according to a positional numbering convention.

Abstract: Broadly speaking, the present invention provides a computer-implemented design method and a system to filter a large selection of mutated antibody sequences, identify those mutated antibody sequences which have particular desired properties, such that the identified sequences can be conjugated to a payload and tested in vitro. Thus, the design and system advantageously remove the need for physical testing of the entire initial selection of molecules, which is complex and costly. Only those which match the pre-defined design criteria may be subject to further experimental testing (in vitro testing) to confirm the results of the computer implemented design. Advantageously, by filtering unsafe molecules during the in silico design process, more time can be spent testing drugs which are predicted to be safe for humans.
