BrdU incorporation and PI analysis of anti-IgM–stimulated B cells from CBA/Ca and xid B mice. The diagram at the top indicates the cell cycle position of cells at the time the cells were harvested. This analysis identifies cells in G0 (G0), S phase (S), and those which have completed S phase and are now in the second cell cycle G0 phase (2nd G0), and apoptotic cells (Apo). B cells from CBA/Ca (top row) and xid (bottom row) mice were stimulated with 25 μg/ml of anti-IgM in the presence of BrdU. Cells were harvested at time points indicated and fixed to permit intranuclear staining of DNA with PI. The initial entry of B cells from xid and CBA/Ca is indicated with an arrow. Analysis was performed on FACSCalibur® using CellQuest software.
