We have created and patented a unique Spodoptera frugiperda insect cell line, expresSF+ cells, to optimize protein production using our BEVS technology. These cells have been extensively characterized and products manufactured from them have received regulatory clearance for human clinical testing in the United States, Japan, Australia, Europe, Canada and elsewhere. A veterinary PCV-2 vaccine produced in our cells is being marketed worldwide, including in the United States, Europe and Japan.
expresSF+ cells do not require serum for growth or storage, and double about every 24 hours in our proprietary serum-free media. Unlike other serum-free insect cells, expresSF+ cells generate high titers of baculovirus. Therefore, a single cell line can be used for production of large quantities of protein.
High density: expresSF+ cells can be grown to a density of 108 cells/ml. At a density of 107 cells/ml, the cells are nearly 100% viable in standard suspension cultures. We have established and patented high density fermentation and fed-batch procedures to maximize protein yield. Under these conditions, cell growth is exponential from 1.5X106 to more than 70X106 cells/ml in serum-free media, and viability remains at least 98%.
Licensing agreements are available to use our expresSF+ cells. Please contact Daniel Adams, Executive Chairman and Global Head of Business Development, at 1-203-686-0800 x303.
