DNAPurificationfromAgaroseGels
1. Separate DNA fragments in an agarose gel cast with 0.5 mg/mL Ethidium bromide. Locate bands with a hand-held long-wave UV lamp.2. Slice the gel with a razor blade above and below the bands of interest. Insert the membrane into the gel at each slice, avoiding air bubbles between the gel and the membrane. The membranes above the bands of interest prevent contamination with higher molecular weight DNA.3. Electrophore......阅读全文
