Sample GSM27283 Query DataSets for GSM27283
Status Public on Sep 01, 2004
Title Sporulation sigmaK mutant Hour 4.5 exp. 1
Sample type RNA
 
Channel 1
Source name sigmaK+ (PE454)
Organism Bacillus subtilis
Extracted molecule total RNA
 
Channel 2
Source name sigmaK mutant (PE455)
Organism Bacillus subtilis
Extracted molecule total RNA
 
 
Description Strains PE455 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. Four 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 PE454 and Cy3-dUTP for the RNA sample from strain PE455.
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 first repetition of the experiment at this time point.
