Accurate and highly sensitive screening of DNA-binding molecules with primer-dimer templates using a real-time PCR analyzer.

We have developed a strategy to detect the DNA-binding affinities of chemical compounds with a real-time PCR analyzer. In this system, the DNA-binding affinities of chemical compounds are efficiency detected by PCR with high sensitivity. To obtain accurate information about the DNA-binding affinities of chemical compounds, primer-dimers prepared in advance are used as templates. The denature temperature is settled to around the melting temperature of the templates.
