When it comes to Next-Generation Sequencing (NGS), sample quality is everything. From maximizing library yields to removing unwanted fragments, DNA size selection is a critical step that directly impacts sequencing accuracy and efficiency.
At AMD Biotech, we understand that researchers need reliable, consistent, and high-performance tools to prepare their samples. That’s why we offer a range of Auto-Mag® Size Selection Kits tailored for diverse workflows — from high molecular weight DNA extraction to precise library fragment selection.
Why DNA Size Selection Matters
During library preparation, DNA fragments of the wrong size can affect sequencing results, increase costs, and lead to wasted reads. By using magnetic bead-based size selection, you can:
- Remove small contaminants like primer dimers and adapter dimers
- Eliminate overly large fragments that could skew data
- Enrich for the target size range to maximize sequencing efficiency
Our Size Selection Solutions
We’ve designed our kits to work seamlessly in your existing workflows, with no protocol changes needed from other commonly used beads.

Tips for Best Results
- Mix thoroughly: Vortex bead suspension before use and pipette mix or vortex with the sample to ensure complete DNA binding.
- Optimize bead-to-sample ratios: Adjust ratios depending on your target size range.
- Elute in the right buffer: Low-salt, low-EDTA buffers work best for downstream applications.
