5-Fluoroorotic Acid (5-FOA) Purification Resistance to ampicillin is conferred

Resistance to ampicillin is conferred by the bla gene which encodes β-lactamase that cleaves the β-lactam bond of the antibiotic

and may be used in cold rooms or incubators

This DNA standard is designed to have the same microbial composition with the cellular version

Bacterial DNA can be reliably quantified in a background of non-bacterial DNA such as fungal

5-Fluoroorotic Acid (5-FOA) Purification Resistance to ampicillin is conferredUsing 5 Fluoroorotic Acid (5 FOA) for the counter selection of yeast is a common genetic screening method. Curing yeast strains of plasmids, plasmid shuffling, allelic replacement, and two hybrid screens are methods that can employ the use of 5 FOA. Otherwise nontoxic to yeast, 5 FOA is converted to the toxic form (i. e., 5 flurouracil) in strains expressing the functional URA3 gene coding for orotine 5 monophosphate decarboxylase that is involved in
