(h-j) Analysis of the IgH/c-Myc translocation frequency in WT and Samhd1 KO CH12F3-2A cells. (h) Schematic illustration of the experimental design for the translocation assay. (i) Southern blot analysis of PCR-amplified fragments with a Myc-specific probe from two independent experiments. (j) Frequency of IgH/c-Myc chromosomal translocations derived from two independent experiments (mean ± sd; Fisher's exact test).
