Effect of UVC radiation on conformational restructuring of human serum albumin.
The study of the influence of UVC-254 nm radiation on spectroscopic and calorimetric properties of human serum albumin in aqueous solutions was conducted. This radiation did not only accelerate aging of albumin solutions but also caused the other qualitative changes. The dose dependent effect on conformational restructuring and thermal stability of albumin for exposure periods from 10 to 60 min was shown. The differences in response to UVC-irradiation between non-defatted and fatty acid-free albumins were found.
