Expression data from murine irf4-/- and irf4+/+ mature B cells purified by magnetic cell separation

Gene expression profiling of murine irf4-/- and irf4+/+ splenic B cells identifies genes regulated by the transcription factor IRF4 in quiescent mature B cells. B cells from 12-week old irf4-/- and irf4+/+ littermate mice were isolated by magnetic depletion of non-B cells from splenic mononuclear cells. RNA was isolated. Labeled cRNA was hybridized to microarrays and genes specifically expressed in irf4-/- vs. irf4+/+ samples.
