Assay Development Scientist, Protein Biochemistry Tarrytown, NY, US Requisition Number:10833BR Employment Type:Regular Employee -Position Summary Known for its scientific and operational excellence, Regeneron is a leading science-based biopharmaceutical company that discovers, invents, develops, manufactures, and commercializes medicines for the treatment of serious medical conditions. Regeneron commercializes medicines for eye diseases, high LDL-cholesterol, atopic dermatitis and a rare inflammatory condition and has product candidates in development in other areas of high unmet medical need, including rheumatoid arthritis, asthma, pain, cancer and infectious diseases. Summary: The Scientist position in Protein Biochemistry will be responsible for the development of Host Cell Protein (HCP) detection and quantitation assays. Host Cell Proteins (HCP) and process related contaminants are biological impurities that may remain in recombinant drug products even after extensive purification. These impurities pose potential safety risks to patients resulting from their known immunogenicity effects. The proper identification and quantitation of these impurities is critical in producing a safe therapeutic. Responsibilities: The individual will be working on developing complex Enzyme-linked immunosorbent assays (ELISA) and CE-western methods to support the detection and quantitation of total HCP in in-process and DS samples. The individual will work with CROs to generate relevant polyclonal antibodies (pAbs) and subsequently develop strategies for purification, modification and characterization of these pAbs. The individual will also use a variety of biochemical and biophysical methods to characterize the critical proteins that are produced to support assay development. The individual will cross functionally work to develop a robust HCP program within Regeneron. Requirements: -Ph.D. in Biochemistry, Biology or other relevant scientific field with 0-2 years of industry experience. -Technical proficiency in protein affinity purification and ELISA development is desirable. -Experience in electrophoresis/immnoblotting techniques, including 2D gels, western blots, WES and/or DIGE is preferred -A strong fundamental understanding of protein structure/function and biophysical chemistry is required. -Excellent oral and written communication skills are required. -Working knowledge or familiarity with HCPs and related issues will be definite plus.
