SUNY ESF Institutional Biosafety Committee: Guidance on the Use of Human, Primate, and Mammalian Cell Lines Objective Human, primate, or mammalian cell lines, even in the absence of overt contamination, may contain adventitious viruses and/or other opportunistic pathogens or zoonotic agents. Since it is extremely Biosafety Level 3 (BSL-3): molecules and cells, organisms and viruses containing such molecules to ensure an optimal protection of public health and of the environment. The document provides clarity on biosafety requirements and recommendations for laboratory facilities such as facility design, 2007-12-25 Human cell lines are commonly used in biomedical research, yet appropriate biosafety requirements for handling human cell lines are often subject to debate within the scientific community. In order to clarify the University’s position on this matter, the Institutional Biosafety Committee (IBC) has created the following guidance. biosafety features of 2nd versus 3rd generation packaging systems. Introduction Lentiviruses, a genus of the Retroviridae family, are enveloped retroviruses that replicate in a host cell through reverse transcription. Lentiviruses are classified as Biosafety Level 2 (BSL-2) organisms due to their ability to infect primary human cells.

Chinese Hamster Ovary (CHO) cells have emerged as the gold standard in the production of biologics. Their unique combination of beneficial quality characteristics make them the ideal cell line to produce many a protein in. Amongst other highly useful factors, the fact that they are easy to grow in large scale cell culture under defined conditions and allow human biosimilar post-translational

For example, T-cells infected with HIV would require Biosafety Level 3 Primary cells from blood or lymphoid cells of human or simian origin Containment level appropriate to the risk ATCC has classified cultures and related products by biosafety level (BSL) for the purposes of packaging for safe shipment. The classification is based on an assessment of the potential risk with regard to U.S. Public Health Service guidelines, background information on the material provided by the depositor, and review of the material by ATCC scientists. Biosafety Level 2: Cells contain adenovirus. Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.

Amongst other highly useful factors, the fact that they are easy to grow in large scale cell culture under defined conditions and allow human biosimilar post-translational Biosafety Level 2 (BSL-2) BSL-2 is appropriate for moderate-risk agents known to cause human disease of varying severity by ingestion or through percutaneous or mucous membrane exposure. Most cell culture labs should be at least BSL-2, but the exact requirements depend upon the cell line used and the type of work conducted: Biosafety Level 3 High Cell lines with endogenous biological agents or cells that have been deliberately infected Containment level appropriate to the agent.

Key to the CHOZN® Platform is the development of the CHOZN® ZFN (Zinc Finger Nuclease) modified cell lines (GS -/- and effects of senescence. However, CHO cells have been proven safe, with the value of products being generated considerably outweighing any associated risks.

However, CHO cells have been proven safe, with the value of products being generated considerably outweighing any associated risks. Downstream processes for CHO cell products have matured to a stage where they can be purified to contain not more than picogram levels of contaminating CHO DNA per dose of the product (26).
