Webthymine-adenine photoadduct has been detected in UV-irradiated DNA as well as in oligo- and poly(dA-dT). The quantum yield for its formation ranges from about 7xlO~4 mole/E in the deoxydinucleoside monophosphate to 1 x 10~5 mole/E in native calf thymus DNA (75); the photoreaction is strongly quenched by base pairing. Webphotochemical reactions, i.e. photoadduct formation and photooxidation of biomolecules, can be useful screening tools. In vivo models under development (modified LLNA-assays and MEST-assay) may become valuable in the future. However, the validation of all these tests is still limited. slr5500 uhf repeater
