Popis: | Summary Transcription factors are important regulators of cell fate and function. Knowledge about where transcription factors are bound in the genome is crucial for understanding their function. A common method to study protein-DNA interactions is chromatin immunoprecipitation (ChIP). Here, we present a revised ChIP protocol to determine protein-DNA interactions for the yeast Saccharomyces cerevisiae. We optimized several aspects of the procedure, including cross-linking and quenching, cell lysis, and immunoprecipitation steps. This protocol facilitates sensitive and reproducible quantitation of protein-DNA interactions. For complete details on the use and execution of this protocol, please refer to (de Jonge et al., 2019). Graphical Abstract Highlights • Chromatin immunoprecipitation protocol to quantify protein-DNA interactions • Optimized for sensitivity and robustness • Optimized for quantitative comparisons between experiments, e.g., in time series • Highlights common ChIP pitfalls, variable steps, and how to increase reproducibility Transcription factors are important regulators of cell fate and function.
