Protein Expression (PERG)
| Current Members | Studies | Activities | Membership History |

The mission of the Protein Expression Research Group (PERG) is (1) to educate ABRF members and scientific community on best practices in recombinant protein expression and purification, and (2) help to advance the technology in recombinant protein expression and purification as a public service for laboratories engaged in protein expression and purification. Scientific areas include eukaryotic expression (baculovirus/insect cells, and mammalian), bacterial expression, cell-free expression, construct design, protein purification (tags, increasing throughput, increasing ease), protein refolding, and cell culture.
