Yоu аre the prоduct mаnаger in a biоpharmaceutical company specializing in the production of recombinant antibodies for various therapeutic and diagnostic applications. In the following, explain which strategies you would use for the creation and production of specific antibody types used for different applications – as exemplified by the projects below. Project A is aimed at selecting and producing antibodies useful to efficiently counter drug poisoning. 1. Describe what type of antibody is commonly used for this application and why (2 pts). 2. What type of expression system would you use for the production of this type of antibody, and why (2 pts)? 3. Your task is to increase the affinity of one these antibodies for drug XYZ using an in vitro affinity maturation system first developed in the mid-1980s. What is the name of this strategy? (1 pt) 4. Briefly describe the strategy named in (3.) including the individual steps that you will be doing as part of this strategy (2 pts). Project B involves the selection and production of monoclonal antibodies for the treatment of breast cancer. This antibody should target the HER2 gene product that is overexpressed in about 30% of all breast cancers. 1. Why do you need to use a full monoclonal antibody for this therapeutic application as opposed to only antibody fragments (killing cancer cells)? (1 pt) 2. Describe how you would obtain a HER2 specific, humanized monoclonal antibody using an in vivo process that has revolutionized and actually enabled the production of monoclonal antibodies. What is the name of this technology? (2 pts)
