Claim: | 1. An isolated nucleic acid molecule comprising two or more identical units consisting of, from 5′ to 3′ direction, a 5′ nucleotide sequence, a human immunoglobulin heavy chain V gene segment, and a 3′ nucleotide sequence, wherein said 5′ nucleotide sequence and said 3′ nucleotide sequence are identical or different, and comprise 20 to 1000 contiguous nucleotides of a spacer sequence from an immunoglobulin heavy chain gene of an animal generating antibody diversity primarily by gene conversion and/or hypermutation, wherein said spacer sequence is SEQ ID NO: 35, and said animal is a rabbit. |
Claim: | 2. The isolated nucleic acid molecule of claim 1 wherein said human immunoglobulin heavy chain V gene segment is a member of the VH3, VH1, VH5, or VH4 family. |
Claim: | 3. A recombination vector comprising a nucleic acid molecule according to claim 1 . |
