12Preparation of template DNASince cycle sequencing can be performed using very little template DNA, onlyvery small amounts of detrimental impurities

13As another example, when using the universal -40 17-mer, which has a meltingtemperature of about 50°C, cycling between 45°C and 95°C is effective. I
