You have been asked to submit a detailed proposal describing the steps for the production of these two products, the proposal should include the following:
 Detailed description of the drug discovery (which approach, which gene, gene accession number if possible), gene manipulation and recombinant DNA technology steps (including which vector, which promoter).
 Detailed description of the required drug characterization, drug delivery system (justify the selection)
 Detailed description of the sources of biopharmaceuticals (justify the selection) & upstream processing (in case you selected bacterial and mammalian cell lines).
