Recombinant protein production by transient gene transfer into Mammalian cells.
The timely availability of recombinant proteins in sufficient quantity and of validated quality is of utmost importance in driving drug discovery and the development of low molecular weight compounds, as well as for biotherapeutics. Transient gene expression (TGE) in mammalian cells has emerged as a promising technology for protein generation over the past decade as TGE meets all the prerequisites with respect to quantity and quality of the product as well as cost-effectiveness and speed of the process. Optimized protocols have been developed for both HEK293 and CHO cell lines which allow protein production at any desired scale up to >100 l and in milligram to gram quantities. Along with an overview on current scientific and technological knowledge, detailed protocols for expression of recombinant proteins on small, medium, and large scale are discussed in the following chapter.
