Synthesis and purification of biotinylated oligodeoxynucleotides containing single TpT dimeric pyrimidine (6-4) pyrimidone lesion

Ultraviolet (UV) radiation could induce pyrimidine-related dimeric lesions in genomic DNA. Though the cyclobutane pyrimidine dimers (CPDs) are the most abundant UV-induced lesions, the pyrimidine (6-4) pyrimidone photoproducts (6-4PPs) may have more serious, potentially lethal, and mutagenic effects. It is important to have 6-4PP-containing oligodeoxynucleotides to be prepared for studying their adverse biological effects. Here, we developed a...
