5-Fluoroorotic acid (monohydrate) (5-Fluorouracil-6-carboxylic acid Mono(hydrate); 5-FOA) 是一种用于分析酵母分子遗传结构中URA3基因的表达。酵母菌若含有活跃的URA3基因(该基因负责编码乳清酸苷-5'-单磷酸脱羧酶),就能将5-FOA转换成对细胞有害的氟脱氧尿苷。当培养基添加尿嘧啶时,具有URA3基因突变的抗性酵母菌株能在5-FOA的环境下生存。

产品描述 | 5-Fluoroorotic acid (monohydrate) (5-Fluorouracil-6-carboxylic acid Mono(hydrate); 5-FOA) is employed to detect the expression of the URA3 gene in yeast molecular genetic constructs. Yeast possessing an active URA3 gene (which encodes orotidine-5'-monophosphate decarboxylase) convert 5-FOA into 5-fluorodeoxyuridine, a substance toxic to cells. Yeast strains with mutations in the URA3 gene that confer resistance can grow in the presence of 5-FOA if uracil is added to the medium. |
