Promoter chip seq
WebA promoter is a DNA sequence that is recognized, bound and initiated by RNA polymerase. It contains conserved sequences required for RNA polymerase-specific binding and … WebApr 6, 2024 · ChIP-seq based approaches allow for assignment of cofactors. However, many Factors have highly non-gaussian ChIP signal distributions; the distributions can have large numbers of sites with very low but detectable signals. This thwarts unbiased attempts to define genes as ‘targets’ or ‘non-targets’ [ 14 ].

WebMethylated DNA immunoprecipitation (MeDIP or mDIP) is a large-scale ( chromosome - or genome -wide) purification technique in molecular biology that is used to enrich for methylated DNA sequences. It consists of isolating methylated DNA fragments via an antibody raised against 5-methylcytosine (5mC).

At each of these loci, we identified MNase-sensitive fragments, with reduced occupancy following depletion of either Smarca4 or Smarca5 , suggesting that nucleosome remodeling factors may create fragile nucleosomes.
