1 mutation in 100 000 wild-types because sensitivity matters

Radically improving cancer diagnostics

Rarity superRCA is an ultrasensitive multiplex assay for detecting rare nucleic acid sequences in biological samples like liquid biopsies. The format and flexibility of the technology platform – and read-out based on flow cytometry – makes it suitable for research as well as clinical application.

Enabling full potential of liquid biopsies

Rarity offers ultrasensitive superRCA® assays for research, available for service testing. The superRCA® assays are designed for extreme sensitivity to enable the full potential of liquid biopsy.

What is superRCA®?

superRCA is an ultra-sensitive and highly specific molecular amplification technology. It is used to detect very small amounts of DNA sequence variants, like cancer mutations, in patient tissue or Liquid Biopsies.

It offers effective detection of multiple targets simultaneously – so called multiplexing. The assay can be performed in most hematology laboratories with existing equipment, using well-established flow cytometry for read-out, enabling more accessible testing with shorter response times.

About us

Rarity Biosciences was founded in 2021 as a spin out from Uppsala University to further develop and commercialize the superRCA assay technology. The superRCA technology was first discovered and developed by PhD Lei Chen and Professor Ulf Landegren in the Molecular Tools group at the Department of Immunology, Genetics, and Pathology.
