Low bias, high fidelity amplification built for NGS Workflows.

Engineered for NGS library amplification, Twist TrueAmp Polymerase delivers uniform coverage across GC extremes, high sensitivity from low inputs, and automation ready hot start performance.

Reliable

Unbiased, High Fidelity Results

Amplify uniformly across extreme 5–95% GC regions to maintain coverage of difficult targets. Improved fidelity and reduced homopolymer slippage deliver cleaner data and more confident calls with fewer repeats.

samples

Reliable Performance from Challenging Samples

Generate consistent, high-yield libraries from complex samples—even at ≤100 pg input—so you recover more usable data and keep your workflows moving forward.

detection

Simplified, Scalable Workflows

An aptamer enabled hot start enables room temperature stability for automation, while a single-tube 2× mastermix simplifies setup and reduces hands-on time; helping you scale workflows with fewer errors and faster turnaround.

Product data

TrueAmp sustains coverage where others drop out, improving sequencing economics and preserving difficult targets.

With improved efficiency, TrueAmp can hit yield targets in fewer cycles, limiting cycle-induced artifacts. It remains robust for low-yield libraries typical of post-capture PCR.

An engineered proofreading polymerase reduces C→T misincorporations often caused by cytosine deamination and limits slippage across long homopolymers—critical for sensitive variant detection.

Magnetic beads are widely used for purification and size selection but can inhibit PCR and lower yields.

Engineered amplification that preserves library complexity

Many PCR enzymes are optimized for single-amplicon tasks (qPCR, cloning) rather than complex NGS libraries.

TrueAmp changes the approach
An engineered proofreading, high-processivity DNA polymerase that delivers best-in-class GC uniformity, yield, and fidelity for library amplification.

The result
Fewer biases toward short, GC-neutral molecules and more usable data per run.
