title: A PCR-mediated method for cloning spot DNA on restriction landmark genomic scanning (RLGS) gel.
abstract: A PCR-mediated direct cloning for target spot DNA from RLGS gel has been established. The method consists of PCR amplification of adaptor-ligated spot DNA fragments without excluding similar-sized DNA fragments co-localized on RLGS gel, and following selective ligation with the NotI-dT vector. Applying this method, we have successfully cloned several DNA fragments derived from target spots whose intensities change developmentally due to DNA methylation in the telencephalon of C3H/HeN mice. Since only a few micrograms of total DNA is sufficient for our spot cloning, our method may be highly useful when the total DNA sample prepared for cloning is limited.
