Themixture is incubated in a water bath at 37⁰C for 15 min and afterwards transferred on ice and 4μl of DNA loading buffer is added. The samples were then run on a polyacrylamide gel electrophoresis which had been pre-run for 30 min. Electrophoresis was carried out at 4⁰C for 3h till the bromophenol blue migrated to 2cm above the bottom of gel. The gel was taken out and kept on Whatman filter paper sheet and covered by saran wrap followed by drying in a gel dryer at 80⁰C for 1h under suction. The dried gel was exposed to phosphoimager screen by keeping in phosphoimager cassette overnight

A binding reaction mixture was prepared by adding the following components to a microcentrifuge tube on ic
