Biotin streptavidin pull down
WebAug 18, 2024 · The promoter pull-down method takes an unbiased, biochemical approach to identify proteins bound to a defined promoter. Proteins are captured by flowing cellular lysate over promoter-bound beads. Positive hits that specifically bind to the target DNA are identified by comparison to a negative control DNA substrate.
