Development of the Yeast Pichia pastoris as a System for the Production of Recombinant Proteins

December 8, 2011
12:30 pm – 2:00 pm EST



Symposium Course Description: The origins of the yeast Pichia pastoris will be discussed along with the logic and research that lead to its eventual development as a host for the production of recombinant proteins. Recent advances in vectors and host strains for its use will be presented. An example of its use, the cloning and expression of a full-length chimeric humanized monoclonal antibody, will be presented.

Learning Objective Bullet Points: 

  • Understand the origin of this yeast system.
  • Learn about recent advances in the system.
  • Learn where information on how to use the system and where various components can be obtained.
  • Understand the strengths and weaknesses of the yeast system with regard to the synthesis of specific types of proteins.


Who Should Attend: 
Researchers of all levels from B.A. to Ph.D. interested in synthesizing recombinant proteins.
