pBridge Description

pBridge is a shuttle vector that replicates autonomously in both E. coli and S. cerevisiae. It carries the bla gene (for ampicillin resistance in E. coli) and the TRP1 nutritional marker that allow yeast auxotrophs carrying pBridge to grow on limiting synthetic medium lacking tryptophan. Note: Yeast strain Y187 is a methionine auxotroph; therefore, haploid Y187 harboring pBridge cannot be grown on medium lacking methionine.
