Title
Sporulation spoIIID mutant Hour 3.5 exp. 1
Sample type
RNA
Channel 1
Source name
spoIIID+ (strain PE456)
Organism
Bacillus subtilis
Extracted molecule
total RNA
Channel 2
Source name
spoIIID mutant (strain PE452)
Organism
Bacillus subtilis
Extracted molecule
total RNA
Description
Strains PE452 and PE456 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. Three 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 PE452 and Cy3-dUTP for the RNA sample from strain PE456. 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.
