内容記述 | Previously we reported that the cells irradiated with ultraviolet (UV) light at S phase revealed the highest transformation and mutation frequencies over various cell phases. In order to understand the mechanisms underlying these high frequencies, we developed an immunological method allowing us to follow the excision kinetics of UV-damage in single cells. Consequently, we established two monoclonal antibodies differentially recognizing each specified UV-damage. At first, the hybridomas between spleen cells from a mouse immunized with UV-DNA and myeloma cells were screened in their binding to UV-DNA and a hybridoma producing antibody against (6-4) photoproduct in DNA was isolated. A further characterization of the antibosy, 64M-1 revealed that it recognizes (6-4) photoproduct of thyminethymine or thymine-cytosine sequence in UV-DNA. Secondary, by the fusion between the spleen cells from a mouse immunized with 313 nm UV-DNA in the presence of acetophenone, a hybridoma secreting antibody directed against thymine-thymine dimer was isolated. The antibody TDM-1 bond to DNA irradiated with 313 nm UV in the presence of acetophenone and to UV-irradiated oligo(dT)_8.
