Plasma cells from spleen were FACS sorted using Blmp1 and CD138 expression and gene expression compared to nave B cells, FACS sorted using B220 and IgD

RNA extracted from plasma cells purified from spleens were examined by Illumina microarray for gene expression. This was correlated with location and stage of differentiation using Blimp1 expression as a divider. All plasma cell samples were then compared to resting follicular B cells.
