Simple size selection for your DNA sample


  • Tunable: High quality tunable DNA fragment size selection from 150 bp to 800 bps
  • Consistent performance: Rapid purification with high reproducibility
  • Automation Ready: Scalable automation-friendly protocol

The Select-a-Size DNA MagBead Kit is a size selection DNA magbead kit that provides the fastest and easiest method to purify specific ranges of DNA fragments from PCR, endonuclease digestions, ligations, library preparations, adapter removal, etc. This simple workflow allows for specific cutoffs that can be modified to suit reaction clean-up, left-sided, right-sided or even double-sided size selection. The Select-a-Size MagBeads kit selectively binds fragments based on the volume of buffer added relative to the sample. Simply choose a desired cutoff to bind the target of interest onto the beads and remove species outside of this range. The desired DNA is easily eluted from the beads following a rapid wash regimen. Choose from one of the pre-determined cutoffs or fine tune the protocol for even more specific selections between these points. Size selections can be performed in as little as 10 minutes to yield high-quality DNA which is suitable for highly sensitive applications including Illumina® Next-Generation Sequencing, and any other sensitive downstream applications. The protocol can be performed manually or using an automated platform for high throughput processing.

Q1: Will this kit work to clean up genomic DNA?

You can use it for genomic clean up, but we recommend the DNA Clean & Concentrator Kit (Catalog No. D4080) instead if it is just genomic DNA. If it is genomic DNA plus smaller DNA fragments, we recommend the Select-a-Size MagBeads.

Q2: Will this kit work to remove genomic DNA and recover smaller DNA fragments?

Yes, the Select-a-Size DNA Clean & Concentrator MagBead Kit will work to remove genomic DNA.

Q3: Is this a comparable product to AMPure®/SPRI beads?

Yes, the Select-a-Size DNA Clean & Concentrator MagBead Kit is a comparable product.
