yeast:Assayingmating
SetupYou have yeast strains that are deficient in mating (eg Ste12 knockouts) and would like to test whether transforming them with a plasmid that contains genes that are supposed to complement the mating deficiency actually restores the ability to mate.PrincipleYou''ll need two strains to use as mating tester strains, one MATa strain and one MATalpha strain; these tester strains should have mutations in an u......阅读全文
