"Culture samples for microarray analysis were added to ice-cold 5% water-saturated phenol in ethanol solution, centrifuged at 6,600 g and the cell pellets flash frozen in liquid N2 before storing at -80 degrees C until required. Total RNA was isolated from the stored cell pellets using the hot phenol method, and labeled Cy3 and Cy5 cDNA was prepared from 16 ug total RNA with 10 ug random hexamer (Integrated DNA Technologies, Inc., Coralville, IA, USA)."
