Serum-free cell culture medium
Introduction
Serum-free mediums allow users to standardize their cell culture conditions. It contains no animal proteins or animal-origin constituents, e.g. FCS (fetal calf serum). The AAV-293 cells are used for AAV-2 production and are usually grown in (among other chemicals, such as nutrients, antibiotics, growth factors) serum supplemented DMEM medium. Regarding Western Blots, size exclusion chromatographies and other (purification) methods, the undefined and also highly variable serum products can disturb or interfere with these methods. Therefore it is useful for many applications to grow AAV-293 cells in serum-free medium. Because our long term goal for AAV vectors is application in human patients, we are also trying to develop new methods to produce pure, uncontaminated AAV particles. The use of FCS to supplement cell culture medium for AAV particle production is problematic because even smallest amounts of animal antigens in the administered drug could lead to a strong immune response in patients.
