WebAdd salmon sperm DNA to the warm prehybridization solution so that the final concentration of DNA is 50 µg/mL. Take the blot out of UV crosslinker and roll it carefully into a hybridization tube. Add prehybridization solution with sperm DNA into the hybridization tube and place it at 42 °C in hybridization oven for 5 h. WebDNA interstrand cross-links (ICL) can be induced both by natural products (e.g., psoralens with UVA) and by chemical agents, some of which are used in chemotherapy (e.g., Carboplatin and mitomycin C). Here, we report the formation of ICL by UV radiation in brominated DNA, but only for very specific conformations. The quantum yields for strand …
