Abstrakt: | Multiple studies in Saccharomyces cerevisiae have measured the levels of gene silencing by inserting the URA3 gene at various loci and selecting against URA3 -expressing cells by 5-flouroorotic acid (5-FOA). However, 5-FOA affects the cellular pools of dNTPs and can produce side effects. To circumvent this issue, we and others have introduced drug-free techniques to detect silent and active gene states. In this study, we compared three drug-free methods based on the expression of fluorescent reporters in the VIIL telomere of S. cerevisiae . Our results point out that only one of these methods is suitable for large-scale drug-free analyses of gene silencing. |
