Invitrogen™ PureLink™ PCR Purification Kit 

Description

The PureLink PCR Purification Kit provides a more convenient, rapid, and high-yielding purification process compared to other companies' kits. After PCR amplification, purification of the PCR amplicons is required for many common downstream applications, including enzyme digestion, ligation, sequencing, and labeling experiments, to prevent enzymes (polymerase, restriction enzyme) and reaction components (dNTPs, primers, buffers, salts) from carrying over, contaminating, and negatively influencing the downstream experiments.

Advantages of the PureLink PCR Purification Kit include:
• 4X binding capacity compared to Company Q; 40 μg for the PureLink kit versus 10 μg from other companies' kits
• No need for tedious sample pH adjustments necessary with other kits
• Convenient and rapid protocol, completed in less than 10 minutes
• Optional size-selection buffers included for selectively purifying 300–600 bp fragments or removing fragments <300 bp

The PureLink PCR Purification Kit is based on the selective binding of dsDNA to silica-based membrane in the presence of chaotropic salts. Simply mix the PCR product with Binding Buffer and apply to the PureLink Spin Column. The dsDNA binds to the silica-based membrane in the column. Remove impurities by thorough washing with Wash Buffer. To purify the DNA, elute the dsDNA in low-salt Elution Buffer or water.The purified PCR product is suitable for automated fluorescent DNA sequencing, restriction enzyme digestion, and cloning.
