    摘要: A method for engineering and utilizing large DNA vectors to target, via homologous recombination, and modify, in any desirable fashion, endogenous genes and chromosomal loci in eukaryotic cells. These large DNA targeting vectors for eukaryotic cells, termed LTVECs, are derived from fragments of cloned genomic DNA larger than those typically used by other approaches intended to perform homologous targeting in eukaryotic cells. Also provided is a rapid and convenient method of detecting eukaryotic cells in which the LTVEC has correctly targeted and modified the desired endogenous gene(s) or chromosomal locus (loci) as well as the use of these cells to generate organisms bearing the genetic modification.

    摘要: Nucleic acid constructs and methods for rendering modifications to a genome are provided, wherein the modifications comprise null alleles, conditional alleles and null alleles comprising COINs. Multifunctional alleles (MFA) are provided, as well as methods for making them, which afford the ability in a single targeting to introduce an allele that can be used to generate a null allele, a conditional allele, or an allele that is a null allele and that further includes a COIN. MFAs comprise pairs of cognate recombinase recognition sites, an actuating sequence and/or a drug selection cassette, and a nucleotide sequence of interest, and a COIN, wherein upon action of a recombinase a conditional allele with a COIN is formed. In a further embodiment, action of a second recombinase forms an allele that contains only a COIN in sense orientation. In a further embodiment, action by a third recombinase forms an allele that contains only the actuating sequence in sense orientation.
