This chapter describes the step-by-step methods employed by the Structural Genomics Consortium (SGC) for screening and producing proteins in the baculovirus expression vector system (BEVS). This eukaryotic expression system was selected and a screening process established in 2007 as a measure to tackle the more challenging kinase, RNA-DNA processing and integral membrane protein families on our target list. Here, we discuss our platform for identifying soluble proteins from 3 ml of insect cell culture and describe the procedures involved in producing protein from liter-scale cultures. Although not discussed in this chapter, the same process can also be applied to integral membrane proteins (IMPs) with slight adaptations to the purification procedure.
