Ultrafree® Centrifugal Filter, 0.5 mL Sample Volume，50PKG，42600，密理博

General 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
