摘要
This disclosure provides, among other things, strategies for minimizing antibody diversification in a transgenic animal that uses gene conversion for antibody diversification. In some embodiments, the animal may comprise a genome comprising an endogenous immunoglobulin light chain locus comprising: (a) a functional immunoglobulin light chain gene comprising a nucleic acid encoding a light chain variable region; and (b) a plurality of pseudogenes that are operably linked to the functional immunoglobulin light chain gene and that donate, by gene conversion, nucleotide sequence to the nucleic acid encoding a light chain variable region, wherein the pseudogenes are upstream or downstream of the functional immunoglobulin light chain gene and encode the same amino acid sequence as the light chain variable region of the functional immunoglobulin light chain gene of (a). In other embodiments, the locus may have a tandem array of coding sequences for the light chain.
