Applications
Detection of URA3 gene expression in yeast
Construction of yeast 2-hybrid libraries
Other areas of yeast genetics including gene replacement, analysis of transposable genetic elements, and identification of gene mutations

5-Fluoroorotic acid is a pyrimidine analogue and used for the selection of Saccharomyces cerevisiae with mutations in the URA3-locus (ura3--cells) and Schizosaccharomyces pombe. Wilde type strains of yeast or mutants with a plasmid carrying the URA3-sequence cannot grow in the presence of 5-FOA. Mutations in the URA3-gene result in the loss of activity of the Orotidin-5'-phosphate decarboxylase.

Working Conc.: 1mg/mL - 500ug/mL (500ug/mL will get higher background)

Normally a minimal medium for 5-FOA-selection is used, since in rich medium (YPD) different URA3+-strains may grow in the presence of 5-FOA.
