DNA can be extracted and purified from agarose gels with different melting points in ∼30 minutes using PureLink® silica membrane-based quick gel extraction columns. PCR clean-up, gel extraction Reagents, consumables, and equipment to be supplied by user Reagents • 96– % ethanol Consumables • mL microcentrifuge tubes • Disposable pipette tips Equipment • Manual pipettors • Centrifuge for microcentrifuge tubes • Heating block, water bath, or thermomixer for gel extraction. 3. Determine the appropriate volume of the gel slice by weighing it in a clean mL microcentrifuge tube. Assuming a density of 1 g/mL, the volume of gel is derived as follows: a gel slice of mass g will have a volume of mL. 4. Add 1 volume Binding Buffer (XP2). 5. Incubate at 60°C for 7 minutes or until the gel has completely melted.
