摘要:
A simple method for modifying genes in a recombination deficient host cell is disclosed. Such modifications include generating insertions, deletions, substitutions, and/or point mutations at any chosen site in the independent origin based cloning vector. The modified gene is contained in an independent origin based cloning vector that is used to introduce a modified heterologous gene into a cell. Such a modified vector may be used in the production of a germline transmitted transgenic animal, or in gene targeting protocols in eukaryotic cells. In particular, high throughput methodology is provided for generating the modified the independent origin based cloning vectors of the present invention.

摘要:
A method of efficiently sequencing multiple exons from complex genomic DNAs is disclosed. The methodology includes the use of bacterial and bacteriophage-derived artificial chromosomes (BBPACs) in novel gene trapping protocols. Targeted gene trapping by homologous recombination, and random gene trapping with the use of a transposon system are exemplified. Included in the invention are methods of preparing a gene map from BBPAC contigs, the resulting gene maps, methods of constructing a cDNA library from BBPAC contigs, and the resulting cDNA libraries.
