Description
In this experiment, total RNA was extracted from asynchronous population of L1210 cells and hybridized to Affymetrix 430A 2.0 arrays in order to obtain an expression profile of these cells. We have previously mapped the replication timing of the entire mouse genome in this cell line, using mouse CGH arrays (see E-MEXP-1022). We wanted to validate in our system the known correlation between early replication and expression and to analyze its extent. To this end, we have measured the expression in the same cell line (L1210 cells). Two biological replicates were hybridized to 2 identical microarrays. Expression levels were highly similar between the 2 replicates (r=0.98).
