Expression of SHIP in B cell subsets. (A) Southern blots of amplified total cDNA prepared from phenotypically defined bone marrow and spleen B cell subsets, as well as total bone marrow (TBM), were sequentially hybridized with probes specific for SHIP and actin as indicated. (B) Signal intensities after hybridization were quantified by PhosphorImager® analysis, and expression levels of SHIP relative to actin were calculated. Average expression levels from two determinations are shown normalized to expression in the B220+c-kit+ population.
