Protein Engineering
& Expression of Recombinant Immunotherapeutics
Our research efforts in this area are conducted
under the Cornell University/ Ludwig Institute for Cancer Research
(LICR) Partnership. Currently, we are exploring a number of parallel
routes for the expression of therapeutic agents that have promise
in the clinic. We are evaluating existing approaches, working to
develop novel and improved techniques for protein expression, and
constructing rational approaches to scale-up these systems.
In our laboratory, a major focus is on the development
and optimization of microbial-based expression systems for tumor antigens
and tumor-antigen-specific antibody fragments and their subsequent downstream
purification. Through the use of our new cGMP-certified Biologics Production
Facility, we will carry out the large-scale production of highly purified
cancer immunotherapeutics suitable for testing in early-phase human
clinical trials.
