Lot-to-lot Testing Services

Lot-to-lot variation is a well-known effect in media production and can occur even in chemically defined media. It can be caused e.g. by change of raw materials, minor changes in the powder production process or the solubilization procedure. Furthermore, lot-to-lot variation can occur due to impurities in raw materials. Components such as amino acids in USP/pharma grade with ≥ 98-99% purity may still contain foreign amino acids and trace metals. To evaluate variation in your media lots, we highly recommend biological performance tests and respective analytics. For that, we can establish and perform routine lot testing.
