the role of riboflavin ( rfn ) , fad or fmn in modulating the antiviral activity of poly r ( a-u ) was examined by the human foreskin fibroblast-vesicular stomatitis virus bioassay in which the concentrations of poly r ( a-u ) was fixed at 0.1 mm or 0.2 mm while the riboflavin , fad or fmn concentration was varied to produce variable rfn ( or fad or fmn ) /ribonucleotide ratios ranging from 1/16 to 2/1 .
