Insect-XPRESS™ medium is a protein-free formulation designed to support the growth of insect cell lines derived from Spodoptera frugiperda (Sf9 and Sf21) and Drosophila melanogaster (S2). Cell densities in excess of 8.3 x 106 cells/mL can be achieved with suspension cultures of Sf9 cells using Insect-XPRESS™ medium and an excess of oxygen. This formulation can also be used for stationary monolayer cultures and shake-flask cultures. Insect-XPRESS™ Medium contains L-glutamine and supports superior production of recombinant proteins when using the Baculovirus Expression Vector System (BEVS). For cryopreservation of insect cells, Insect-XPRESS™ can be mixed 50:50 with Cryoprotective Medium (Cat. No. 12-769E). For Research Use Only (RUO) and not approved for human or veterinary use or for use in clinical or in vitro diagnostic procedures.

• Optimal solution for proteins with post translation modifications
• Ease of scale up
• Functionality of proteins similar to native mammalian proteins
