title: Cloning of rat kangaroo (PTK2) cells following laser microirradiation of selected mitotic chromosomes.
abstract: Mitotic chromosomes of rat kangaroo cells were irradiated with a green argon laser microbeam without prior dye sensitization. Deoxyribonucleic acid-negative chromosome paling was observed. The irradiated cells were isolated and cloned into viable populations.
