Freeze 'N Squeeze DNA Gel Extraction Spin Columns

Overview

Freeze 'N Squeeze Method
Freeze 'N Squeeze Recovery

Recovery of DNA fragments using Freeze 'N Squeeze spin columns. Extracted fragments were rerun on a ReadyAgarose 1% TAE gel (lanes 2–6). Lane 1, precision molecular mass ruler; lane 7, EZ Load 100 bp PCR molecular ruler.

PCR Product and DNA Fragment Purification Guide

Bio-Rad offers a variety of pre-PCR and post-PCR sample preparation and cleanup columns and prepacked columns; many are also suitable for DNA fragment purification.

Freeze 'N Squeeze DNA gel extraction spin columns provide a quick and effective means to purify double-stranded DNA fragments from TAE- or TBE-buffered agarose gels. Unlike other purification methods which are often time-consuming or utilize toxic chaotropic materials, the Freeze 'N Squeeze spin column method purifies via filtration, using short centrifugation to draw 50–23,000 bp of DNA out of agarose gel slices that have been quickly frozen and thawed.

Key Features

  • Requires less than 1 minute of hands-on time and less than 10 minutes for DNA cleanup
  • No solutions to prepare
  • DNA immediately available for subsequent PCR, subcloning, ligations, and sequencing reactions
Applications Recovery of DNA fragments purified from TAE- or TBE-buffered agarose gels
Starting material ≤700 mg gel slice
DNA size 50–23,000 bp
Method Spin-column extraction of frozen-thawed gel slices
Recovery 4–23 kb: >80% recovery
Time required <10 min
