Project description:Sulfolobus solfataricus P2 was grown aerobically, with O2 concentrations ranging from 1.5 to 26 % (v/v; gas phase). To gain some insight in control of the respiratory system, transcriptomes of the strain cultivated in different O2 concentrations (1.5 % vs 21 %, 1.5 % vs 26 %) were compared using a DNA microarray approach.

To gain some insight in control of the respiratory system, transcriptomes of the strain cultivated in different O2 concentrations (1.5 % vs 21 %, 1.5 % vs 26 %) were compared using a DNA microarray approach. Two-condition experiments: 1.5% O2 vs two other O2 concentrations (21 or 26% O2). Biological replicates independently grown. One replicate per array. Dye swaps.
Project description:Experimentally mapped transcriptome structure of Sulfolobus solfataricus P2 by hybridizing total RNA (including RNA species <200 nt) to genome-wide high-density tiling arrays (60 mer probes tiled every 25 nt).
Project description:Experimentally mapped transcriptome structure of Sulfolobus solfataricus P2 by hybridizing total RNA (including RNA species <200 nt) to genome-wide high-density tiling arrays (60 mer probes tiled every 25 nt). Sulfolobus solfataricus P2 growth curve experiments were conducted in batch culture. Reference samples were cultured at mid-log phase (OD600 = 0.312). Eight samples were collected that spanned the key phases of the growth curve. Total RNA from samples of growth curve and reference were directly labeled with Cy3 or Cy5, and were hybridized to the tiling array. Dye-flip experiments were done for each sample. Log ratios were calculated for each probe (growth curve sample/reference). Transcriptome browser is available at http://baliga.systemsbiology.net/enigma/.
