AMSBIO (Cambridge, Mass.) has launched a complete new range of commonly used human cytokines and growth factors. Unlike most other commercially-available cytokine products, ActiveMax cytokines are expressed exclusively in human cells under strict animal-free and xeno-free conditions. Therefore, they are uniquely suitable for human cell culture and assay development.
Endotoxin and other non–human components can provoke immune response in human systems. These contaminations are significant complicating factors for human cell culture experiments, in particular those relevant to human cell therapy or other clinical applications. AMSBIO ActiveMax cytokines are exclusively produced in a serum-free, animal component-free and chemically defined cell culture system. These cytokines are absolutely xeno-free, and have an endotoxin level of less than 1.0 EU per microgram.
