Amphioxus Cell Technologies

Amphioxus Cell Technologies was a biotechnology company specializing in the isolation, characterization, and distribution of primary human and animal hepatocytes. Founded in 1995, the company provided essential cell-based models and services for drug metabolism, toxicology, and pharmacology studies to the global pharmaceutical industry. Amphioxus was a pioneer in developing proprietary methods for the cryopreservation of liver cells, allowing researchers to maintain metabolic activity in vitro for extended periods. These high-quality cell products became critical tools for ADME (Absorption, Distribution, Metabolism, and Excretion) testing during the drug discovery process. The company was acquired by CellzDirect in 2001, and its technology eventually became a core part of Thermo Fisher Scientific's hepatocyte portfolio.
