Abstract:
A monoclonal antibody (TDM-2) specific to a UV-induced cyclobutane pyrimidine dimer has previously been established. We investigated here the structural requirements of antigen recognition by the antibody using chemically synthesized antigen analogs. TDM-2 bound to the cis-syn, but not the trans-syn thymine dimer, and recognized not only the cyclobutane ring but also the 5'- or 3'-side phosphate groups flanking the cyclobutane dimer site. The antibody showed strong binding to photodimer-containing single stranded DNA but indicated little binding to double stranded DNA.
