Mutagenesis by retroviral insertion in chemical mutagen-generated quasi-haploid mammalian cells.

Abstract excerpt

Diploidy is a major obstacle to the mutagenic analysis of function in cultured mammalian cells. Here, we show that 6-8 rounds of chemical mutagenesis generates quasi-haploid cells that can be used as targets for insertional mutagenesis using a specially designed retroviral vector that permits rapid identification of disrupted genes in each cell that bears a phenotype of interest. The utility of combined chemical...
