MilliporeSigma™ Ultrafree™-DA Centrifugal Filter

Description

• Recover 100 to 10,000 bp DNA from agarose gel slices in a single 10-minute spin
• The kit consists of a pre-assembled filter device with an agarose gel nebulizer, a microcentrifuge vial, and modified TAE gel extraction buffer (dry).The device utilizes gel compression to extract DNA from the agarose
• Centrifugal force collapses the gel structure, drives the agarose through a small orifice in the gel nebulizer and the resultant gel slurry is sprayed into the sample filter cup.Prepared DNA requires no further purification for most applications, including cloning and radioisotopic or fluorescent DNA sequencing
• Since agarose gel electrophoresis has high resolving power, the small and large non-specific amplification products that frequently interfere with cloning and sequencing after PCR are completely removed from the product
• Minimal hands-on time 10-minute spin Fully-functional DNA Performance Typical DNA Recoveries from Agarose Gels DNA Size (bp) Percent DNA Recoveries 100 78 700 71 1000 77 2027 47 4361 35 9416 32 23130 29 Protocol 1
• Excise the band of interest after routine electrophoretic analysis of PCR products or other DNA through an agarose gel
• 2
• Place the gel slice into the pre-assembled device
• Note: Protocol is not compatible with low melting point agarose
• 3
• Spin at 5,000 x g for 10 minutes to extract gel slurry into filter cup
• 4
• DNA can be stored in the capped filtrate vial after discarding the sample filter cup and gel nebulizer.
