In this protocol, we present a qualitative assay for monitoring the level of expression of β-galactosidase, an enzyme encoded by the LacZ gene, in yeast. This is useful both for determining autoactivity of LacZ expression in yeast DNA “bait” strains and for assessing LacZ reporter gene activation mediated by a transcription factor “prey” … docfa 4.00.5 java
