(f) Effect of deoxyribonucleoside supplementation individually or in combination on the frequency of IgH/c-Myc translocations in CH12F3-2A cells (n = 2; mean ± sd; Fisher's exact test; ns = not significant; *** = p ≤ 0.001). The concentration dNTPs used for supplementation either individually or in combination were as follows: 2′-deoxyguanosine (dG), 0.15 mM; 2′-deoxyadenosine (dA), 1.0 mM; 2′-deoxycytidine (dC), 12 mM; and 2′-deoxythymidine (dT), 1.6 mM.
