For each state in each cell type (20 states, total), fifty 400mers were sampled to represent genomic regions ... We used the ChIP-String assay to make replicate measurements of 5 ng of ChIP DNA, derived using K562 cells and H3K4me3 antibody. We found that ChIP-String assay values were ...
Webplot2DO is very useful for inspecting the degree of digestion in MNase-seq and MNase-ChIP-seq experiments. Figure 6 shows three examples of 2DO plots that originate from an under-digested sample, a properly-digested sample, and an over-digested sample. Figure 6. Plot2DO offers a quick quality check for MNase-seq experiments.

WebMar 8, 2024 · Eukaryotic DNA replication initiates during S phase from origins that have been licensed in the preceding G1 phase. Here, we compare ChIP-seq profiles of the licensing factors Orc2, Orc3, Mcm3, and Mcm7 with gene expression, replication timing, and fork directionality profiles obtained by RNA-seq, Repli-seq, and OK-seq. WebDAP-seq is an in vitro TF-DNA binding assay that allows low-cost and rapid generation of genome-wide binding site maps for a large number of TFs, while capturing gDNA properties that impact binding in vivo. A DAP-seq gDNA library is prepared by attaching a short DNA sequencing adaptor onto purified and fragmented gDNA ( Figure 1 A; DAP library).
WebFeb 23, 2024 · To perform peak calling for each replicate, we used ‘ChIP-seq’ function, implemented in MACS2 v2.1.1 ( Feng et al., 2012 ), with input group as control. For narrow peak such as H3K4me3, we determined reproducible peaks between replicates using irreproducible discovery rate (IDR) ( Babu et al., 2011; Li et al., 2011 ).
IDR is an open source tool available on GitHub. It is a Python program that has already been installed on O2. The first thing we need to do is load the module (and all dependency modules) to run IDR: Now let’s move into the chipseq/resultsdirectory and create a new directory for the results of our IDR analysis. … See more The first step is taking our replicates and evaluating how consistent they are with one another. To run IDR we use the idrcommand followed by any necessary parameters. To see … See more Once you have IDR values for true replicates, you want to see how this compares to pooled replicates. This is a bit more involved, as it requires you to go back to the BAM … See more The user manual provides guidelines on IDR thresholdswhich are recommended for the different types of IDR analyses.
