AMPure XP Workflow

AMPure XP Workflow

Product Features


AMPure XP removes unwanted contaminants from DNA in a variety of applications including PCR, NGS, cloning, and microarrays.

High Recovery

Efficient recovery of your sample ensures that critical data is not lost within the workflow.

Gold Standard for NGS Workflows

Trusted and recommended reagent for size selection and cleanup steps within a variety of NGS workflows.

Flexible and Scalable

Manual cleanups using AMPure XP require less than 30 minutes. For higher throughput needs, AMPure XP is automated on all Biomek platforms enabling hundreds of samples per day.

Don't Lose Critical Data

When so much more has been invested in your research, AMPure XP is the only choice for purification and clean-up steps. Loss of yield during this critical step leads to loss of discovery in your research.

Relative costs of the different steps required to perform various NGS applications. Steps include Extraction, Library Construction, Library Enrichment, Clean-up, and Sequencing. Costs were calculated based on average list price of commercially available kits and reagents in 2017. Clean-up efficiencies were calculated by determining the total DNA yield by Picogreen Assay after performing a clean-up procedure on a known amount of DNA. The percent yield relative to AMPure XP performance was then used to calculate the impact of efficiency on various commercially available library construction methods and a change in purification reagent.

AMPure XP - Keep Critical Data For Downstream Applications

AMPure XP is the Gold Standard for Bead Based, Next-Generation Sequencing (or NGS) Cleanup

Over 200 library prep kits suggest using AMPure XP, including kits from trusted sequencing companies:

  • Illumina®
  • Nanopore
  • PacBio
  • Thermo Scientific

Over 15,000 publications used AMPure XP, referenced in articles in Science, Nature, and PNAS.

Nucleic acid purification and cleanup are mandatory for genomic applications, such as sequencing, qPCR/ddPCR/PCR, and microarrays. Maximizing recovery, consistency, and speed, AMPure XP meets the stringent needs of today’s genomic applications and minimizes the risk of losing important genetic information.

  • High recovery of amplicons greater than 100bp
  • Efficient removal of unincorporated dNTPs, primers, primer dimers, salts and other contaminants
  • Predictable and consistent size selection

“Our findings suggest AMPure XP would be the best choice for analyses requiring very high analytical stringency.” Mikheikin, A., Olsen, A., Picco, L. et al.
