Gene Expression Profiles of RAW264.7 Macrophages Stimulated with Two Commonly Used Preparations of LPS

For each treatment (Sigma LPS, LIST LPS, and media only), three biological replicates (separate macrophage cultures and RNA isolations) were profiled. Each sample was labeled with Cy3 and Cy5 and co-hybridized with Stratagene Universal Mouse Reference (dye flip techical replicates). Expression at 2 timepoints (6 and 24 hours post-treatment) was assessed.
