The challenge:

The limits of conventional detection

In this space, you are searching for mutations that should not exist — measuring against a baseline of zero.

Detecting such rare signals demands ultra-sensitive technologies capable of identifying a single malignant cell among hundreds of thousands, or even millions. Enabling new and improved research applications.

Transforming
mutation detection

Because sensitivity matters

superRCA is a patented dual-RCA technology that amplifies single mutated DNA molecules into large, fluorescent particles. This enables quantifiable detection of mutations with a sensitivity of 1:100,000 — up to 100× more sensitive than conventional methods.

Up to 100‑fold higher sensitivity, powered by three core factors

High DNA input

Sensitivity follows the math: your limit of detection is directly determined by the amount of material available. More input means deeper insight.

Multifactor genotyping

A robust error‑correction strategy that eliminates false signals and delivers exceptionally low background noise.

High event counts

Measuring a large number of molecular events increases precision and ensures reliable data even at ultra‑low variant levels.

Innovation without investment

Seamlessly fits into your lab workflow

superRCA assays are simple to run, whether manually or fully automated, using standard laboratory equipment or widely available automation platforms.

Detection is performed on conventional flow cytometers, a technology with over 75,000 instruments installed globally, ensuring broad accessibility and seamless integration into existing lab workflows without the need for any larger investments.

Scientifically validated

by leading researchers

Leading researchers spanning a multitude of disciplines have evaluated and implemented our mutation detection platform, resulting in numerous peer-reviewed publications. Through these independent studies, the technology has consistently demonstrated strong analytical performance and high sensitivity.

This continuously growing body of evidence represents a real‑world confirmation from respected experts and their findings reinforce the potential of the platform and highlight its value for applications where sensitivity truly matters.
