Zymo Research Corporation 5-Fluoroorotic Acid (5-FOA), 5g

Supplier: Zymo Research Corporation F90015

Curing yeast strains of plasmids, plasmid shuffle, allelic replacement, and two-hybrid screens are standard methods employing 5-FOA (Boeke, J.D. et al. 1984 and 1987; Vidal, M. 1997). The nontoxic 5-FOA compound is converted to toxic 5-flurouracil in yeast strains expressing a functional URA3 gene (orotine-5’- monophosphate decarboxylase), whose normal cellular function is in the synthesis of uracil. Practically, strains that are phenotypically Ura+ become Uraand 5-FOAR (resistant), after selection.
