The ratio was determined by comparing the peak intensities in LC-MS runs of UVB versus dark conditions (UVB/Dark). The number of peptides assigned a Mascot score above 35, as well as the protein mass, score and empAI value, are also listed for each identified protein. (D: down-regulated; U: up-regulated).
