This work describes the novel use of tolC as a selectable/counter-selectable marker for the facile modification of DNA in Escherichia coli. Expression of TolC (an outer membrane protein) confers relative resistance to toxic small molecules, while its absence renders the cell tolerant to colicin E1. These features, coupled with the lambdaredgam recombination(More)
Several late stages of the oligodendrocyte (OL) developmental lineage can be identified immunologically in the newborn rat brain. However, OL lineage-specific markers are not available for the detection of the less mature, yet determined, OL precursors. We have developed a retrospective bioassay, combining limiting dilution analysis with a novel culture(More)
