title: Propagation of two species of mitochondrial DNA in chinese hamster-mouse somatic cell hybrids.
abstract: Mouse-hamster hybrid cells were analyzed for the species of mitochondrial DNA (mtDNA) retained using Southern blotting and hybridization with highly labeled mitochondrial DNA probes. Initial analyses were performed as soon as there were 10(7) cells, which took between five and eight weeks from the time the fusion was performed (approximately 23 cell doublings). The majority of clones tested had detectable levels of both mouse and hamster mtDNA at first testing.
