Purification of G Protein Subunits from Sf9 Insect Cells Using Hexahistidine-Tagged α and βγ Subunits

  • Tohru Kozasa


G protein-mediated pathways are the most fundamental mechanisms of cell signaling. In order to analyze these pathways, the availability of purified recombinant G proteins are critically important. Using Sf9-Baculovirus expression system, a general and simplified method to purify various G protein subunits is described in this chapter. This method is useful for purification of most of G protein subunits.
