The Complete Comparison: HighPrep PCR for PCR Cleanup and NGS Library Preparation Savings

Part 3: Bringing cost, DNA recovery, and Workflow compatibility together

Changing a familiar SPRI bead-based reagent is not a decision most sequencing laboratories make based on price alone. But, a lower-cost alternative still has to answer several important questions:

Will it recover DNA reliably? Will it support different bead-to-sample ratios? Will size-selection behavior remain predictable? And can it fit into an existing PCR cleanup or NGS library preparation workflow?

Across this three-part series, we have examined those questions from three perspectives:

Cost. Performance. Workflow practicality.

Now we can bring the results together.

1. The Cost case: Small per-library savings become significant at NGS scale

In Part 1, we examined an illustrative NGS library preparation workflow consuming 150 µL of magnetic bead-based reagent per library.

At the evaluated 500 mL list pricing:

• Leading SPRI bead-based reagent: approximately $2.56 per library
• HighPrep PCR: approximately $1.37 per library
• Potential savings: approximately $1.19 per library

That represents an estimated 46% reduction in SPRI bead-based reagent cost (at 500 mL list-price).

The difference becomes especially relevant in high-throughput environments:

 For laboratories performing repeated PCR cleanup, NGS library purification, and magnetic bead-based DNA cleanup, seemingly small reagent savings can therefore have a substantial cumulative effect.

2. The Performance case: Comparable DNA recovery across multiple bead ratios

Cost savings would mean little if the performance of purification and selective size selection of DNA suffered.

That is why Part 2 compared HighPrep PCR with the Leading SPRI bead-based reagent at 1.8x, 1.0x, 0.9x, and 0.8x bead-to-sample ratios using 1,250 ng DNA input.

Across the tested conditions, HighPrep PCR demonstrated:

• Closely comparable recovered DNA yields
• DNA recovery rates from 67.4% to 81.2%
• Similar gel-based DNA purification profiles
• Comparable ratio-dependent fragment retention
• Slightly higher recovered yields at 1.8x, 0.9x, and 0.8x in this evaluation

At the 1.0x ratio, recovered DNA yield differed by only 5 ng, while recovery rate differed by just 0.4 percentage points.

Taken together, the results showed broadly comparable purification behavior across the evaluated bead-to-sample ratios.

3. The Workflow question: Can it fit into existing PCR cleanup processes?

Performance data are important, but day-to-day usability matters too.

HighPrep PCR is a paramagnetic bead-based reagent designed for efficient DNA purification, tight DNA size selection, NGS library clean-up, and Oxford Nanopore Technologies® (ONT) Library Preparation Cleanup. 

At the standard 1.8x bead-to-sample ratio, the workflow follows the familiar magnetic bead-based purification approach used for routine PCR product cleanup: DNA binds to paramagnetic beads, unwanted reaction components are removed, the beads are washed, and purified DNA is eluted for downstream use.

This makes HighPrep PCR relevant for applications including:

• PCR product purification
• Amplicon cleanup
• DNA purification
• NGS library preparation
• Post-PCR purification
• Ratio-dependent DNA size selection

For laboratories already familiar with magnetic bead-based DNA cleanup, this can simplify evaluation because the underlying purification approach remains familiar.

What does the complete comparison tell us?

For sequencing laboratories and high-throughput research teams, the strongest alternative is not simply the cheapest reagent or the reagent producing the highest value in a single experiment.

The real goal is balance.

A practical PCR cleanup reagent should provide:

Reliable purification performance. Predictable bead-ratio behavior. Workflow compatibility. And sustainable cost per sample.

Across the conditions evaluated in this series, in Comparison to the Leading SPRI Bead-Based Reagent, MagBio’s HighPrep PCR demonstrated:

• Comparable DNA purification across four bead-to-sample ratios
• Closely matched recovered DNA yields
• Reliable recovery rates
• Similar gel-based purification and selective DNA size-selection profiles
• Familiar magnetic bead-based workflow characteristics
• Approximately 46% lower reagent cost in the evaluated 500 mL list-price comparison

For high-throughput genomics laboratories, that combination can make HighPrep PCR worth evaluating as an alternative to the higher-priced Leading SPRI Bead-Based Reagent.

The most important comparison is your own

Every laboratory is different.

Sample types vary. PCR products vary. NGS library preparation methods vary. Automation platforms, instruments, fragment distributions, and acceptance criteria vary as well.

That is why published comparison data should be the beginning of an evaluation, not the end.

The most useful test is to compare reagents in your own PCR cleanup or NGS workflow.

Measure what matters to your laboratory:

• DNA yield
• DNA recovery
• Fragment profile
• Purification consistency
• Bead-to-sample ratio behavior
• Automation compatibility
• Cost per sample

Validate HighPrep PCR in your workflow

MagBio Genomics offers laboratories the opportunity to request a HighPrep PCR evaluation sample at no added cost, allowing you to perform a side-by-side comparison using your own samples.

Instead of asking whether a lower-cost magnetic bead reagent might work, you can measure the answer directly. By comparing the recovery, cleanup, and cost.

For laboratories processing thousands of PCR reactions or NGS libraries, the result could have a meaningful impact on both workflow performance and operating cost.
