Comparison of direct elution and amplification to SDS elution followed by decross-linking and purification for H3K27ac. a Representative signals of enrichment for a TSS (left) and distal site (right). b Scatter plot of reads at TSS for the two different elutions and amplifications from the same lobChIP sample. c Comparison of enrichment at TSS for the directly eluted lobChIP sample and a sample done with standard ChIP-seq protocol. Read counts on x- and y-axis are normalized to sequencing depth.
