“…ChIP assays were performed as previously described [33], except that the glycine, the formaldehyde, and the sodium phosphate mix were sparged with argon gas for minutes before use to maintain anaerobic conditions when required. Samples were immunoprecipitated using of RNA Polymerase antibody from NeoClone (W0004).…”

“…Comparison of fixed-cell images with images from live-cell procedures, including the use of microfluidic device, not only validates the fixed-cell technique, but also highlights the advantage and necessity in using the fixed-cell procedure to probe the organizations of the transcription machinery and the nucleoid in fast-growing cells (Jin et al, 2015). Note that the formaldehyde-fixed cells procedure has also been widely used in ChIP-chip assays to study the distribution of E. coli RNAP genome wide under different growth conditions (Davis et al, 2011; Grainger et al, 2005; Herring et al, 2005). Importantly, the fixed-cell images are consistent with extensive studies of E. coli genetics and physiology (Jin et al, 2013).…”

“…Several methods and review articles describe in detail how to perform ChIP-chip and ChIP-seq experiments [30-33], and we encourage readers to also review these publications. The methodology described in these articles differs and while each has been used to produced high-quality ChIP-seq data, we have found success following the method described by Davis et al [33]. Briefly, cells are grown in desired conditions to a designated growth phase and formaldehyde is added to crosslink proteins to DNA.…”

“…The method used for immunoprecipitation of the cross-linked DNA bound transcription was described by Davis et al [33]. Since library preparation and sequencing are still expensive and can take weeks to obtain data depending on access to sequencing cores, pilot experiments to examine the efficiency of ChIP before subjecting the samples to ChIP-seq are critical.…”
