  • Effects of trypsin on cellular, chromosomal and DNA damage induced by X-rays 

    Sprunt, Elizabeth A. (University of St Andrews, 1990) - Thesis
    When cells are trypsinized before irradiation, potentiation of cell killing is seen; this is known as the 'trypsin effect'. The trypsin effect is re-examined here in the light of experiments in which enzymatic modifications ...
