Dominant negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into cells and transgenic animals, new cell lines and animal varieties with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation. These methods are useful for generating genetic diversity within immunoglobulin genes directed against an antigen of interest to produce altered antibodies with enhanced biochemical activity. Moreover, these methods are useful for generating antibody-producing cells with increased level of antibody production. The invention also provides methods for increasing the affinity of monoclonal antibodies and monoclonal antibodies with increased affinity.
A method of increasing affinity of a monoclonal antibody for an antigen comprising substituting an amino acid within the variable domain of the heavy or light chain of said monoclonal antibody with a second amino acid having a non-polar side chain, whereby said affinity of said monoclonal antibody for said antigen is increased.
A method of increasing affinity of a monoclonal antibody for an antigen comprising substituting an amino acid within the variable domain of the heavy or light chain of said monoclonal antibody wherein said amino acid comprises a non-polar side chain, with a proline, whereby said affinity of said monoclonal antibody for said antigen is increased.
