Interaction Term : DAP-seq [MI:2288] PSI Molecular Interactions

Description  DAP-seq is an in vitro TF-DNA binding assay in which a DAP-seq gDNA library is prepared by attaching a short DNA sequencing adaptor onto purified and fragmented gDNA. In a separate reaction, an affinity-purified TF is prepared by in vitro expression, bound to ligand-coupled beads, and washed to remove non-specific cellular components. The gDNA library is added to the affinity-bound TF and the unbound DNA is washed away. The bound fraction is eluted, amplified with PCR primers to introduce an indexed adaptor, and the DNA is sequenced. Namespace  PSI-MI
