title: GSM1934005: SirA - ChIP-exo; Salmonella enterica subsp. enterica serovar Typhimurium str. 14028S; OTHER
library_construction_protocol: E. coli and S. Typhimurium cells (at mid-exponential growth phase) were fixed with formaldehyde (1% final concentration) for  20 min at 30°C with shaking. The crosslinking reaction was then quenched by the addition of glycine (0.33M final concentrationg) for 5 minutes at room temperature with gentle mixing.  Cells where then lysed on ice with lysozyme and sonication. Samples were used for on-bead enzymatic reactions of the ChIP-exo procedure and Illumina Tru-seq sequencing libraries were construction as described in Rhee and Pugh, 2012
