Biosimilars are recombinant proteins produced by genetically modified cells and are made to be a copy of the original biotherapeutic reference product or “innovator” and to share quality attributes with the innovator. Therefore, the discovery and expression of a functional CpSFP-PPT enzyme clearly indicates that recombinant parasite ACP domains could be activated by CpSFP-PPT, thus clearing the path for the future functional analyses, including the determination of the final product(s), of CpFAS1 and CpPKS1 using recombinant proteins. November 19, 2020. RECOMBINANT THERAPEUTIC PROTEINS 2.
