A new procedure for T specific cleavage of DNA fragments utilizing photoreaction with spermine has been described. Irradiation of 3'-[32P]-end-labeled DNA fragments for 10-20 min with a germicidal lamp emitting mainly 254-nm light in the presence of 1 M spermine in distilled water resulted in a T specific cleavage of the DNA chains. This method does not require piperidine treatment. By contrast, when the DNA fragments were irradiated in the presence of methylamine under similar conditions, both G and T bands with the intensity of G greater than T have appeared. A similar but less selective T cleavage has also been observed in the irradiation of 5'-[32P]-end-labeled DNA fragments in the presence of spermine followed by brief heating of the photolysate in a loading buffer for gel electrophoresis. The T specific photoreaction with spermine and the G greater than T reaction with methylamine described here may be conveniently used in combination with the standard Maxam-Gilbert's reactions to provide independent confirmatory readings.
