title: Comparison between inactivated Sendai virus, polyethylene glycol and Tween 80 as permeabilizing agents for introduction of neurospora endonuclease into X-irradiated cells.
abstract: Inactivated Sendai virus, polyethylene glycol and Tween 80 were employed as agents to make X-irradiated CHO cells permeable for Neurospora endonuclease, in studies designed to evaluate the influence of this enzyme on the frequencies of X-ray-induced chromosome aberrations. Polyethylene glycol and Tween 80 were found not to be very efficient in making cells permeable. Besides, polyethylene glycol was found to increase the frequencies of X-ray-induced chromosomal aberrations.
