Sample GSM27278 Query DataSets for GSM27278
Status Public on Sep 01, 2004
Title Sporulation gerE mutant Hour 5.5 exp. 3
Sample type RNA
 
Channel 1
Source name wild type (PY79 strain)
Organism Bacillus subtilis
Extracted molecule total RNA
 
Channel 2
Source name gerE mutant (PE454 strain)
Organism Bacillus subtilis
Extracted molecule total RNA
 
 
Description Strains PY79 and PE454 were grown in parallel in hydrolysed casein medium at 37°C to an OD600 of 0.6. Sporulation was induced by resuspension in Sterlini-Mandelstam medium at 37C. Five hour and thirty minutes after resuspension, 25 ml of each culture were collected for RNA isolation and immediately mixed with an equal volume of methanol at –20C.
RNA was isolated with a Hot Phenol/Trizol procedure.
cDNA was prepared from 50 ug tot RNA and fluorescently labeled using Superscript Reverse Transcriptase and Cy5-dUTP for the RNA sample from strain PY79 and Cy3-dUTP for the RNA sample from strain PE454.
Protocols for RNA isolation, cDNA preparation and labeling, hybridization to the microarrays and washing procedure can be found at http://mcb.harvard.edu/losick
This is the third repetition of the experiment at this time point.
