About us

The story about Rarity Bioscience

Rarity 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)

Sustainability at Rarity Bioscience

Our vision is to democratize mutation detection. By offering fast, sensitive, and reliable mutation detection technology we support diagnostics and treatment of genetic diseases – aiming to facilitate accessible and affordable healthcare to all. 

We provide precision diagnostics capabilities as the Rarity superRCA technology enhance targeted analysis of point mutations. This also makes it extremely useful in drug development and target therapy assessment. Our products can be an enabler for detection and precision medicine for cancer care. 

The superRCA technology has been developed to be operated using existing lab equipment to further support sustainability. Assay read-out is done using a flow cytometer, instrumentation that is commonly used in clinical and research settings to identify and quantify cells. It is a strategy for sustainable consumption and production to utilize equipment already available at standard labs. It also means that samples do not have to be sent to distant specialty labs due to lack of local capacity or availability.

At Rarity Biosciences we are committed to creating a sustainable workplace culture that prioritizes a healthy and inclusive culture. We are pleased to have a diverse team that represents different backgrounds and perspectives, and we are actively working to ensure equal representation in leadership. To support our employees’ physical and mental health, we provide a wellness hour that allows them to focus on their personal wellbeing. We also organize team-building activities, promoting collaboration and teamwork. 

We are committed to make sustainability part of everything we do, and we are constantly looking for new ways to promote a healthier workplace and contribute to a more sustainable world.
