Searching for gene expression data by cell line I have two cancer cell lines (OCI-Ly18 &amp; riva) that I want to find gene expression data for, but I'm not aware of many gene expression databases that allow searching by cell-line without searching by gene.

I tried Genevestigator on the recommendation of this thread
but found no data on either cell line.

What would be the best way to find gene expression data for these cell lines?
Try the Gene Expression Omnibus - it looks like they have some datasets.
