Preparation of radioiodinated simian virus 40 DNA for use in DNA - DNA reassociation kinetics experiments.
A method is described for the preparation of 125I-labelled SV40 DNA. Using this method, SV40 DNA can be routinely labelled to 15 - 10(6) dpm per mug; much higher specific activities are easily obtained by minor modifications of the method. Once incorporated, the radioactive label dissociates from DNA exceedingly slowly at 4 degrees C or at 68 degrees C. Iodinated SV40 DNA is shown to be useful in the quantitation of viral nucleic acid sequences in SV40-transformed 3T3 cells by DNA - DNA reassociation kinetics.
