| 摘要 |
The invention is directed toward a method of producing a selected cell line or a non-human transgenic animal model for the analysis of the function of a gene comprising introducing into an embryonic stem cell a vector having a selectable marker which, when the vector is inserted within a gene, the inserted vector can inhibit the expression of the gene, selecting embryonic stem cells expressing the selectable marker, excising the vector from the embryonic stem cells expressing the selectable marker such that host DNA from the gene is linked to the excised vector, sequencing the host DNA in the excised vector, comparing the sequence of the host DNA to known gene sequences to determine which host DNA is from a gene for which a model for the analysis of the function the gene is desired, selecting the embryonic stem cell containing the inhibited gene for which a model for the analysis of gene function is desired, and forming a cell line or a non-human transgenic animal from the selected embryonic stem cell. The invention is also directed toward a method of selecting a cell for the analysis of the function of a gene. The invention is also directed toward libraries of cells, cell lines, and transgenic animals produced using cells produced by the methods disclosed herein. |
