The company - About us

The story about Rarity Bioscience

The company was founded 2021 based on a discovery by Dr Lei Chen, PhD in molecular biology and a member of Professor Ulf Landegrens team at the Department of Immunology, Genomics and Pathology at Uppsala University.

Discovery in molecular biology

Rarity Bioscience 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 in 2015 by PhD Lei Chen and Professor Ulf Landegren in the Molecular Tools group at the Department of Immunology, Genetics, and Pathology. The initial aim was to continue the successful development of padlock probe and rolling circle amplification to generate secondary rolling structures that could increase the signal intensity of existing protocols. 

Rarity Bioscience – the story

As with most scientific discoveries, the path is not always straight, but the superRCA came out as an extremely powerful amplification tool with unique allele distinction suitable for single variant mutation detection. 

The first application in Leukemia was studied together with Uppsala Academic Hospital and SciLifeLab during 2018-2020 as a retrospective benchmarking study that showed that the Rarity superRCA was able to detect common mutations in Acute myeloid leukemia (AML) with a greater sensitivity than current test practice i.e. ddPCR and NGS. In addition, a study of multiple follow-up samples showed that relapse could have been detected up to three months earlier. (Lei et al. Nature Communication)

Vision & Mission

Our vision is to democratize mutation detection.

Our mission is to improve clinical decisions and patient outcome by offering fast, sensitive, and reliable mutation detection technology at the right time.
