Molecular beacon was employed here to convert the ligation information into fluo-rescence signal quickly and quantitatively. This method pro-vides effective and original approach to researching the dy-namic ligation process and the interactions between nucleic acids and ligase. An analytical method for T4 DNA ligase based on this way has been built up with a linear detection range from 2.3×10-4 U/mL to 0.23 U/mL. It is rapid and sensitive to detect 2.8×10-5 U T4 DNA ligase in 10 min.展开更多
