Can anyone tell me what is the best way to label a circular plasmid (probably supercoiled) with radioactive label. I tried nick translation but the labeled mixture after passing through sephadex column and running a gel seems to have all oligonucleotides. I need to keep the DNA as a circular plasmid. Thanks.. Please reply at kroy@bme.jhu.edu Thanks.. Krish Roy .
