Favorite PCR Clean-Up Kit to Use
Choosing a preferred PCR clean-up kit depends on specific needs, but many experts favor the Zymo Research DNA Clean & Concentrate kit for its effectiveness and low elution volume. Other notable options include Machery-Nagel NucleoSpin kits, magnetic bead-based cleanups, and NEB DNA clean-up kits. Each offers unique advantages tailored to different workflows.
Zymo Research DNA Clean & Concentrate Kits
Zymo kits are popular for their reliable performance. Users appreciate the minimal elution volume option as low as 6 μL, which helps concentrate the PCR product effectively. Many labs buy Zymo columns separately because they are often high quality and sometimes rebranded by distributors. The consensus is that if a method works well, there may be little reason to switch.
Machery-Nagel NucleoSpin Kits
Machery-Nagel offers durable spin columns with lids, which simplify labeling during processing. Many users select this brand for convenience rather than pure performance differences. It fits well in labs that prefer clearly labeled plasticware.
Magnetic Bead Clean-Up (SPRI)
For high-throughput workflows, magnetic bead-based cleanups are favored. SPRI methods, such as AMPure XP by Beckman Coulter or Kapa Pure by Roche, provide efficient size selection and purification. Beads capture DNA fragments over a size threshold, and adjusting ratios allows flexibility in recovery. Users note the need for magnet racks suitable for 0.2 mL tubes or 96-well plates, which makes this method ideal for numerous samples.
NEB DNA Clean-Up Kit
NEB columns receive praise for higher yield compared to some competitors like Thermo or Qiagen. Users report better DNA concentration recovery when using NEB, making it a preferred choice when yield is critical.
Other Kits and Enzyme-Based Clean-Up
- Thermo Fisher kits are versatile, supporting PCR cleanup, plasmid prep, and gel extraction with consistent results.
- Qiagen kits are often reserved for cleaning restriction digests due to their specific strengths rather than routine PCR clean-up.
- ExoSAP-IT is an enzyme-based alternative, suitable when direct PCR cleanup prior to sequencing is desired without column purification steps.
- Other affordable options include NZYTech Gelpure and Econospin columns combined with homemade buffers.
Summary of Key Takeaways
- Zymo kits are favored for low elution volumes and consistent performance.
- SPRI bead clean-up suits high-throughput labs needing speed and size-selectivity.
- NEB kits outperform some rivals in DNA yield.
- Thermo Fisher and Qiagen kits are trusted but more specialized.
- ExoSAP-IT offers a simple enzymatic cleanup alternative.
What makes Zymo PCR clean-up kits popular among users?
Zymo kits offer low elution volumes, sometimes as low as 6 µl. Their columns are trusted and often rebranded by other suppliers. Users find them reliable and consistent.
How do magnetic bead clean-up methods compare to spin columns?
Magnetic beads, like AMPure XP, allow for easier processing of many samples at once. They also enable size selection and work well with multichannel pipets. A magnet rack is needed for these setups.
Which PCR clean-up kit is recommended for high DNA recovery?
NEB DNA clean-up kits are noted for yielding higher DNA concentrations compared to some others like Thermo Fisher or Qiagen. They have quality columns that improve recovery rates.
Are there any advantages to using Machery-Nagel NucleoSpin kits?
Machery-Nagel kits come with spin columns that have lids, making labeling easier. This convenience appeals to users managing many samples.
Can enzymatic clean-up methods replace traditional kits?
ExoSAP-IT is a popular enzymatic option that cleans PCR products with a simple incubation. It avoids purification steps and yields good sequencing results.
What are some budget-friendly PCR clean-up kit alternatives?
NZYTech Gelpure and Econospin columns offer cost-effective options. Some labs combine these columns with leftover or separately bought buffers to save money.
