Abstract:
1. A transgenic rabbit, comprising a humanized immunoglobulin locus comprising multiple Ig gene segments wherein (a) at least one of said gene segments is a human Ig gene segment comprising two or more identical or different units consisting of, from 5′ to 3′ direction, a 5′ nucleotide sequence, a human immunoglobulin heavy or light chain V gene segment, and a 3′ nucleotide sequence, wherein said 5′ nucleotide sequence and said 3′ nucleotide sequence have the nucleotide sequence of SEQ ID NO 35; (b) said gene segments are juxtaposed in an unrearranged, partially rearranged or fully rearranged configuration, and (c) said humanized Ig locus is capable of undergoing gene rearrangement, if necessary, and gene conversion and/or hypermutation, and producing a repertoire of humanized immunoglobulins in said transgenic rabbit.
