You did all the hard work extracting DNA and prepare it for sequencing. Your PCR works perfectly. Your library prep looks solid. But then you get your sequencing output and those short unwanted fragments are everywhere in your data.

You know the problem
AmpliClean™ LF solves this
Building on NimaGen's proven magnetic bead technology as a trusted drop-in alternative to AMPure® XP, AmpliClean™ LF is specifically optimized for long DNA fragments with a size-selection range of 1 - 6 kb. While standard cleanup beads struggle with efficient size selection in this range, AmpliClean™ LF is engineered from the ground up to bind long fragments efficiently and remove short contaminants superior to competing beads.

Why AmpliClean™ LF outperforms standard beads
Superior fragment cleanup
AmpliClean™ LF removes unwanted short DNA fragments more efficiently than competing magnetic beads and our standard AmpliClean™ kit. The optimized bead formulation ensures reliable size selection in any NGS workflow, giving you cleaner data with less background noise.
Cost-effective performance
Delivers superior long-fragment cleanup at a competitive price point, making it an economical choice for both routine and high-throughput sequencing applications.
Customer-validated performance
Real-world data from customer applications shows a market improvement in sequencing output. In full-length 16S sequencing with Oxford Nanopore Technologies, the first customers showed complete removal of contaminating DNA fragments between 400bp - 1000bp.
The workflow you know, now optimized

AmpliClean™ LF follows the same trusted three-step process you rely on:
- Bind – Long DNA fragments (1-6 kb) selectively bind to paramagnetic beads
- Wash – Salts, primers, dimers, nucleotides, and short contaminants are removed with ethanol
- Elute – Ultra-pure DNA is recovered, directly ready for downstream applications
No centrifugation. No vacuum filtration. Just reliable, high-quality DNA in three simple steps.
Automation-ready for any lab
Whether you run manual single-tube workflows or high-throughput sequencing facilities, AmpliClean™ LF adapts to your setup. Fully compatible with Alpaqua® magnet plates and liquid handlers, making it ideal for labs scaling up their NGS operations.

AmpliClean™ LF vs. AmpliClean™ standard beads
Independent comparison shows AmpliClean™ LF delivers:
- Significantly improved removal of fragments <1 kb
- Improved sequencing output, thereby reducing cost
- Consistent performance across different fragment size ranges
