ChIP-chip of MG1655 with antibody against E. coli RNAP beta subunit under various conditions

ABSTRACT: We integrated RNAP binding regions (RBRs) and mRNA transcript abundance to determine segments of contiguous transcription originating from promoter regions. To measure RBRs at a genome scale, we employed a ChIP-chip method to E. coli K-12 MG1655 grown in the presence or absence of rifampicin under multiple growth conditions using antibody against E. coli RNAP beta subunit. Overall design: A twelve ChIP-chip study using immunoprecipitated DNA (IP-DNA) from four separate culture conditions with and/or without rifampicin treatment. The high-density oligonucleotide tiling arrays used were consisted of 371,034 oligonucleotide probes spaced 25 bp apart (25-bp overlap between two probes) across the E. coli genome (NimbleGen). Experiments were conducted as biological duplicates or triplicates (different cultures).
