Experimental Protocol


Pneumococcal biofilms compared to planktonic control at 4, 12, 24, 48 hours. 3 biological replicates each of 4 and 12 hour time points, and 2 biological replicates each of 24 and 48 hour time points. Flip dye (technical replicates) performed for 4, 12, and 24 hour time points; no technical replicate performed for 48 hour time point due to limiting material. Ratios were determined by averaging across technical and biological replicates. The following hybridizations made up each biological replicate: 14090167.tav.annot and 14090190.tav.annot (4hr biol rep 1); 14090169.tav.annot and 14090176.tav.annot (4hr biol rep 2); 14090192.tav.annot and 14090188.tav.annot (4hr biol rep 3); 14087688.tav.annot and 14090180.tav.annot (12hr biol rep 1); 14090185.tav.annot and 14090168.tav.annot (12hr biol rep 2); 14090191.tav.annot and 14090174.tav.annot (12hr biol rep 3); 14090170.tav.annot and 14090175.tav.annot (24hr biol rep 2); 14090193.tav.annot and 14087687.tav.annot (24hr biol rep 3); 14090181.tav.annot (48hr biol rep 1); 14090187.tav.annot (48hr biol rep 2)
