Plasmodium falciparum parasites, strain IT/R29, were selected for (R29R+) or against (R29R-) rosetting. Both cultures (R29R+ and R29R-) were tightly synchronised before a timecourse experiment was performed. 6 samples, named time points 1 to 6, were taken every 8 hours. 12μg of RNA from the R29 non-rosetting parasites at each of the 6 time points was combined together to form the reference pool. The pool and 12μg of each individual time point sample from both rosetting and non-rosetting parasites were then used for cDNA synthesis. For microarray hybridizations,each cDNA sample was coupled to Cy5 (red dye) while Cy3 (green dye) was added to the pool. Cy5-labelled time point samples were mixed with the same amount of Cy3-labelled pool sample. The solution was loaded on a microarray slide and hybridized for 14–16 h.
