title: [Electrophoresis of DNA fragments renatured and cross-linked with psoralen: kinetic analysis of DNA photocross-linking].
abstract: The kinetics of photoreactions between DNA and psoralen was analysed. A method is described for determining the dependence of the average number of cross-links per base-pair (n) on the fluence of UV-irradiation. This calibration curve allows to specify the conditions of irradiation necessary to obtain any desired value of n.
