Research & Services | The Protein Expression Facility

Danieli Tsafi, HUJI, Faculty of Science, The Wolfson Foundation Centre for Applied Structural Biology


Genetics, gene cloning, protein production



The facility functions as a resource and training center for scientists in the fields of gene construction and protein production


Research provided

* Specialization in four major expression systems for a wide variety of applications:

  • Bacterial cells: Optimization of expression conditions in a wide variety of vectors and E.coli strains
  • Insect cells: Specialized baculovirus facility, using the latest developments for optimization of expression for both secreted and non-secreted proteins
  • Mammalian cells: Production of high-titer lentiviruses for induction of primary cells and live animals
  • Cell-free expression: Production of up to several milligrams of proteins in E.coli and wheat-germ based lysates

* Individual training programs in the fields of gene construction and protein expression

* Annual graduate-level workshops in protein expression and purification



  • State-of-the-art technologies, equipment and scientific support to all research laboratories at The Hebrew University, other universities and biotech companies

  • Implementation and development of technologies in gene cloning, protein production, and mammalian cells involving gene silencing, reporter genes
