    摘要: The present invention provides improved methods and compositions for the generation of transgenic non-human animals. The present invention permits the introduction of exogenous nucleic acid sequences into the genome of unfertilized eggs (e.g., pre-maturation oocytes and pre-fertilization oocytes) by microinjection of infectious retrovirus into the perivitelline space of the egg. The methods of the present invention provide an increased efficiency of production of transgenic animals with a reduced rate of generating animals which are mosaic for the presence of the transgene.

    摘要: The present invention relates to the expression and screening of genomic DNA sequences encoding uncharacterized genes and proteins. The present invention provides systems utilizing unique features of retroviral replication to analyze uncharacterized genes derived from genomic DNA samples. In preferred embodiments, a segment of genomic DNA is inserted between 5null and 3null viral long terminal repeats (LTRs) in a vector (e.g., a plasmid, cosmid, or artificial chromosome vector). The resulting vector (or library of vectors containing a plurality of independent genomic sequences) is then introduced into a retroviral packaging cell. The resulting provirus or proteins expression from the provirus are then analyzed.

    摘要: The present invention relates to the production of antibody libraries. In particular, the present invention relates to the use of integrating retroviral vectors to generate libraries comprising a plurality of combinations of antibody light chains and heavy chains. The present invention thus provides improved methods of generating and screening antibody libraries comprising large numbers of unique antibodies.
