Proven Expertise

Founded in 2002, Cellex Incorporated is a biotech company that develops technologies, instruments and assays for testing of human diseases and conditions, particularly for point-of-care (POC) professional healthcare settings. Based in Morrisville, NC, the company maintains both a GMP manufacturing site in Suzhou, China (ISO 13485 certified, FDA QSR) and an exclusive manufacturing partner in Zhengzhou (Hunan Province).


Pioneering Technologies

Founder James Li and the Cellex team had already created a lineage of more than 50 pioneering diagnostic test successes on multiple platforms (drug resistance, UTI, TB, MI and others) when the COVID-19 outbreak began.
