I am looking to conduct differential gene expression analysis comparing one cell line to many others. However I would like to have multiple replicates (5+ or so) for each cell line. It is possible to download samples from many different GEO datasets, but I would have to conduct extensive data normalization to make a fair comparison, and I want to avoid that. Does anyone know of a data source (i.e. one dataset) from which I might obtain gene expression data with MANY SAMPLES PER CELL LINE? Thanks!
