title: Assignment of the native Chinese hamster dihydrofolate reductase gene to chromosome 2.
abstract: The native Chinese hamster DHFR gene was localized to 2pter----q14 using a combination of somatic cell hybrid technology and molecular techniques. In addition, PGD, ENO1, and DTS, previously mapped to Chinese hamster chromosome 2, were localized to 2q14----qter. Localization of PGM1 to this region was confirmed. The relationship of the site of the native DHFR gene to the location of the homogeneously staining region in methotrexate-resistant cells is discussed.
