  1. 1. Parallel protein purification at the mg scale• Introduction Emerald Bio• Concepts & workflow• Multi-target parallel processing• Automated parallel protein purification Peter Nollert, Ph.D. Chief Technology Officer Emerald Bio pnollert@embios.com May 3, 2012 8th Annual Protein Engineering Summit - PEGS 11/16/2012 Copyright 2012 Slide 1
  2. 2. Our Protein X-ray Crystallography Structure Output April 15: 482 SSGCID.org Emerald is depositing 1 new structure every 1.7 days11/16/2012 PEGS 2012 Slide 2
  3. 3. SSGCID: the Most ProductiveStructural Genomics Center in 2011 1.5 2.0 2.5 3.0 Resolution (Å)3/20/2012 PEGS 2012
  4. 4. MTPP: Multi-Target Parallel Processing >100 structures delivered, >60 ligand bound 13 different targets crystallized MTPP and Quality Average Resolution: 2.3Å Average MolProbity: 94 percentile11/16/2012 PEGS 2012 Slide 4
  5. 5. Hundreds of Structures Require Thousands of Proteins 684 vector constructs 220 different proteins purified 9.7g = total protein produced 5g11/16/2012 PEGS 2012 Slide 5

  8. 8. High-throughput parallel protein purificationwith the Protein MakerApplications: Antibody Purification from up to 1 Liter load • Biomarker discovery (immuno depletion) • Parallel expression and purification testingParallel Protein Chromatography • Carries out up to 24 purifications / run • One step purification or two step purification (up to 12 samples) • Uses standard 1-5 mL chromatography columns in parallel • Unattended operation, up to 4 runs / day • Small (1mL) to large (1L) load volumes 11/16/2012 PEGS 2012 8 US Pat.# 6,818,060
  9. 9. Protein Maker: Automated Parallel Protein PurificationThroughput:Multiple targets & variants are Target variation:provided in batches Purification of internal deletion variants; His-taggedApproach: Parallelchromatographic IMAC purification Analysis:of 24 target protein • SDS-PAGE • Crystallization Lysates Eluates Crystals 11/16/2012 PEGS 2012 9
  10. 10. Protein Maker: Parallel lysis scouting Problem: Standard lysis buffer may not Example render all protein targets soluble. Sample: Cytochrome P450 Solution: Test 12 different cell-lysis buffers insoluble in standard lysis buffer followed by small scale (1 mL) IMAC Result: of 12 lysis buffers 2 yield purification soluble CYP51A (CHAPS/bOG + 500 mM NaCl) Lyse E.coli Ni-IMAC cells in 12 standard SDS-PAGE Scale-up different elution analysis cell lysis buffers protocolSmith, E., et al.
