Fig 3. 3’RR core enhancers ectopically promote CSR in vitro.
(A) Comparison of κ-CSR efficiency as evaluated by counting LPS in vitro stimulated mCκ+ spleen B-cells (gated on B220+ cells) by flow cytometry from KIKS and c3’RR-KIKS mice.(B) as in (A) for LPS/IL4 in vitro stimulation. Percentages are given with mean+/- SEM. Mann-Whitney test for significance.
