RS rearrangement levels are highest in late pre–B cells. (a) Vκ-RS rearrangement levels quantified in bone marrow subsets from C57BL/6 mice (n = 5). (b) Vκ-RS rearrangement levels assayed in less mature (BP-1+; gray bar) and more mature (BP-1; black bar) Fr. D B cells of C57BL/6 mice (n = 3). All PCR reactions were performed in duplicate. Data are depicted as fold difference (+SEM; **, P ≤ 0.01) relative to the mean RS level in C57BL/6 splenic B220+ IgM+ κ+ B cells (dashed lines). Bone marrow B cell fractions were obtained by flow cytometry, as shown in Fig. S1 (available at http://www.jem.org/cgi/content/full/jem.20082053/DC1).
