Figure 4From: DNA double-strand break induction in Ku80-deficient CHO cells following Boron Neutron Capture ReactionRepresentative images of nuclear γ-H2AX foci in the CHO-K1 (A) and xrs-5 (B) cells at 30 min after 2Gy of BNCR with 25ppm BPA compared with 1Gy gamma irradiation. Many large foci were observed in the cells exposed BNCR (open arrows). The bar represents 20 μm.Back to article page
