Kantaro’s COVID-SeroKlir Antibody Test Named as a Finalist for Fast Company’s 2021 World Changing Ideas Awards

Kantaro Biosciences, LLC, a joint venture between the Mount Sinai Health System and RenalytixAI (LSE: RENX / NASDAQ: RNLX), announced today that COVID-SeroKlir, its semi-quantitative SARS-CoV-2 IgG antibody test, was named as a finalist in the Pandemic Response category of the 2021 World Changing Ideas Awards.

COVID-SeroKlir measures the presence and precise level of IgG antibodies against the receptor-binding domain and the full-length spike protein — the same type of antibodies produced as part of the immune response to COVID-19 virus exposure or generated by a vaccine. Unlike most other antibody tests, COVID-SeroKlir reports a numerical answer, not just a yes/no qualitative result. It is a high performing test that can be used in any authorized clinical testing laboratory without the need for proprietary equipment.

“Our focus from the beginning of COVID-19 was to make the Kantaro antibody test broadly accessible worldwide to help determine public health strategies and inform healthcare decision making,” said Sara Barrington, chief commercial officer, Kantaro. “We are honored to be recognized by Fast Company for our Pandemic Response efforts and continue to pursue our goal in helping the world emerge from the pandemic.”

Kantaro achieved a variety of milestones since the company’s launch in May 2020, including launching COVID-SeroIndex for research use only; a commercial partnership with Bio-Techne Corporation (NASDAQ: TECH) to manufacture, sell and distribute the Kantaro tests at scale; CE marking for COVID-SeroKlir and COVID-SeroIndex; and Emergency Use Authorization by the FDA for COVID-SeroKlir. Through strategic partnerships, Kantaro also established a global presence in the UK, Europe and South America.
