Stem Cell Related Patent Number US6528313
| Title: | Procedure for specific replacement of a copy of a gene present in the recipient genome by the integration of a gene different from that where the integration is made | | Inventors: | Le Mouellic, Herve; Paris, France
Brulet, Philippe; Maurepas, France | | Summary: | This invention provides for the specific replacement of a gene by targeted insertion of a heterologous gene carried on a vector having homologous flanking sequences which reconstruct the complete gene. The method relates to a process for targeted replacement of at least a part of an endogenous gene by at least a part of a foreign gene. Further disclosed are the properties of the vector, the first and second flanking DNA sequences, and methods of selection and transfection. This represents a continuation of previous applications filed by the same assignee and inventors. | | Abstract: | The present invention relates to a process for targeted replacement of at least a part of an endogenous gene by at least a part of a foreign gene or targeted insertion of at least a part of a foreign gene at a targeted site in an endogenous gene in a cell by homologous recombination. This process includes (A) providing a vector which contains (1) at least a part of the foreign gene which is heterologous with respect to the endogenous gene; (2) a first flanking DNA sequence homologous to a first genomic sequence situated on one side of the part of the endogenous gene to be replaced or the targeted site; and (3) a second flanking DNA sequence homologous to a second genomic sequence situated on the other side of the part of the endogenous gene to be replaced or the targeted site, the foreign gene being located between the first and second flanking DNA sequences and is complementary to the part of the endogenous gene to be replaced; (B) transfecting a cell with the vector; (C) and selecting a transfected cell that contains the foreign gene at the targeted site or where the part of the endogenous gene is to be replaced. | | US Patent Website: | Click Here for Full Text of Patent | | Title Number: | US6528313 | | Application Number: | US1994000301037 | | Date Filed: | 06/09/1994 | | Date Published: | 04/03/2003 | | Assignee: | Institut Pasteur, Paris, France |
