“The influence of water soluble polysaccharide from spirulina platensis on excision repair of DNA was investigated by means of endonuclease assay and radioautography. The results showed that the presence of the polysaccharide enhanced significantly both the repair activity of radiation damaged DNA excision and the unscheduled DNA synthesis (UDS). During the examination of the time course of the excision process, it was found that the presence of polysaccharide of spirulina not only increased the initial rates of the damaged DNA excision and the UDS, but also postponed the saturations of both important reactions of excision and repair DNA synthesis.” – Qishen, P. et al.
