Type II Experimental Design:

The use of a common control cDNA probe allows the relative expression of each gene to be compared across all samples.
In each microarray hybridization experiment, fluorescent cDNA probes were prepared from an experimental mRNA sample (Cy5-labeled) and a control mRNA sample (Cy3-labeled) isolated from a pool of 9 lymphoma cell lines:
