The influence of pH on the excision of UV-photoproducts from HeLa cells.
Excision of pyrimidine dimers with pH decreasing in UV irradiated HeLa cells can be depressed. This depression is independent of the UV dose within the investigated range. The excision capacity of HeLa repair system from absolute amount of excised dimers is shown.
