| Number | Title | Issue Date |
| 7005299 | Expression of heterologous genes according to a targeted expression profile A gene trap vector comprises a DNA construct containing an expression unit of an internal ribosome binding site (IRES) coupled to a heterologous gene sequence; this expression unit is used in gene trap protocols to obtain expression of the heterologous gene in the h... | 02/28/2006 |
| 6878542 | Isolation, selection and propagation of animal transgenic stem cells Animal stem cells are obtained and maintained by culturing cells containing, in the genome, a selectable marker; differential expression of the selectable marker enables preferential survival and/or division of the desired stem cells compared to non-stem cells. ... | 04/12/2005 |
| 6150169 | Expression of the heterologous genes according to a targeted expression profile This invention relates to DNA constructs for inserting heterologous gene sequences into a host genome so as to obtain expression of the heterologous gene, to methods of inserting heterologous gene sequences into a host genome, and to organisms carrying mo... | 11/21/2000 |
| 6146888 | Method of enriching for mammalian stem cells Mammalian stem cells are obtained and maintained in vitro whose genome has at least one nucleic acid construct encoding an antibiotic resistance gene operatively linked to a promoter specific for mammalian stem cells. The preferential expression of the an... | 11/14/2000 |
