  • Recombinase Mediated DNA modifications
    Patent number: 6245565
    Abstract: Nucleoproteins comprising overlapping homologous DNA sequences coated with a recombinase are employed for introduction into cells to produce double D-loop structures. The sequences may be modified with various moieties which result in modification of DNA. Formation of the D-loops results in inhibition of replication and transcription, where the moieties can be employed for permanent scission or modification of the DNA. The methods and compositions can be used for investigating physiological processes, for producing animal models, and for inhibition of an undesirable phenotype in vivo.
    Type: Grant
    Filed: April 28, 1999
    Date of Patent: June 12, 2001
