    摘要: The present invention concerns a method of identifying genetically modified mammalian cells using a mutated protein-tyrosine kinase receptor (PTKR) as a selectable marker in mammalian cells. Particularly preferred mutated PTKR selective markers are mutated epidermal growth factor receptor (EGFR) family members, and muscle specific tyrosine kinase receptor (MuSK-R) family members. Further a method for the immunoselection of transduced mammalian cells is disclosed comprising retrovirally transducing mammalian cells with a nucleic acid sequence encoding a mutated EGFR, incubating the transduced cells with a marked antibody which recognizes and binds specifically to the mutated PTKR, and identifying the marked transduced cells.
