Specifically engineered for high performance and yield, Gibco Sf-900 III SFM supports Sf9 and Sf21 cells in both baculovirus and stable expression systems, all in a serum-free environment. This animal-origin-free medium minimizes the risk of adventitious agents and simplifies regulatory processes. It fosters Sf9 cell growth up to densities of 10 to 14 × 106 cells/ml.
