Web4. Make the solution cool down before solidification. 5. Add ethidium bromide (EtBr) to a final concentration of approximately 0.2-0.5 μg/mL (Stocks are generally 10 mg/ml, and require 5 µL stock/100 mL gel). 6. Ethidium bromide binds to the DNA and you could visualize the DNA under ultraviolet (UV) light. CAUTION: EtBr is a known mutagen.
WebTwo method were implemented in determining the binding constant of EtBr to DNA. The first method was by inputting the absorbance data using a fixed excel worksheet. The main goal was to manipulate the value in cell I24 to be as low as possible. After several trails and error, the final value of cell I24 was 0.00011316 and logK was 3.99. population whatcom county waWebEthidium bromide binds DNA by intercalating between base pairs, ...
