After the CPEP course you should know how to:

  • Plan and successfully execute your project. Bring your own project(s)*!!!
  • Make efficient use of bioinformatics tools for planning and analysis of protein expression projects
  • Design PCR primers and codon optimize genes
  • Apply various fast cloning and mutagenesis techniques
  • Use medium-throughput approaches for cloning and protein expression in E. coli
  • Carry out fast parallel cloning of your gene(s) into vectors containing different tags and fusion proteins
  • Use of fusion proteins and associated purification strategies
  • Test for optimal protein production: different strains, growth conditions and fusion partners
  • Co-express components of protein complexes and their purification strategies
  • Prepare and use of auto-inducing medium
  • Do protein expression mini-screens
  • Scale-up positive screening candidates to a protein midi-preparation using purification machines
  • Trouble shoot problems and apply strategies to solve them
  • Apply special protein labeling techniques, such as 15N-labeling for quick NMR analysis
  • Crystallize proteins
  • Interpret simple NMR measurements
  • Carry out electron microscopy sample preparation e.g. negative staining techniques
  • Participants will be guided to present short seminar talks of selected topics.

Special emphasis for the 2020 course

  • Protein expression in eukaryotic cells
    • Expression in Human Embryonic Kidney (HEK) cells (Alexej Schmid)
    • Expression in Baculovirus infected Sf9 cells (Gunter Stier)
    • Expression in plant cell suspensions (Laszlo Bako)

Additional demonstrations and seminars will include the use of:

  • Protein purification with “Äkta” and BioRad machines
  • Protein stability measurement using Thermofluor assay (Melanie Oelker)
  • The Mosquito crystallization robot, crystal imaging facility (Uwe Sauer)
  • NMR characterization of 15N labeled proteins (Anders Öhman)
  • EM facility – first approach to electron microscopy measurements (Linda Sandblad)

(*) If you bring your own project(s), please contact the instructors at least 2 weeks before the start of the course, no later than January 15, 2020). It is also possible to work on a project provided by the course leaders.
