CHO cells are the preferred host expression system for the commercial-scale production of complex biopharmaceuticals (antibodies, enzymes, growth factors, etc.). The aneuploid, proline-requiring CHO-K1 line is a stable subclone of the parental CHO cell line derived from the ovary of an adult Chinese hamster (Puck et al, 1958).

In the case of multi-year research projects involving risk group 3 materials, the Principal Investigator must submit a new application form, even if the activities involving the biological materials have not been altered or modified since the previous submission. 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.

The following list contains human or primate cells that are to be See next page for Biosafety Level 2 cell cultures. Page 2. MATERIAL SAFETY DATA SHEET. American Type Culture Collection. Emergency Telephone: Product Testing for CHO-Derived.

CHO-CD36 cells express high levels of human CD36 (a ligand for erythrocytes infected with the human malaria parasite, Plasmodium falciparum).

The biosafety levels, thus, might differ from one region to another. As per the CDC, biosafety levels are of four types depending on the risk associated with the microorganism and the facilities available. The levels of containment range from the biosafety level 1 (BSL-1), which is the lowest to the level 4 (BSL-4), which is the highest

3 All laboratories at Anschutz Medical Campus are designed at Biosafety Level 2 containment, at a minimum, with unni-directional inward airlflow (negative pressure Cells stored for more than 1 day at −80°C quickly lose viability. If properly banked, cells are guaranteed for six months in liquid nitrogen. Storage Buffer: Recovery™ Cell Culture Freezing Medium (Invitrogen #12648-010). Biosafety Level: 2 Instrument Settings: The GeneBLAzer® ADRA1A CHO-K1 DA Cells requires a fluorescence Human embryonic kidney 293 cells, also often referred to as HEK 293, HEK-293, 293 cells, or less precisely as HEK cells, are a specific cell line originally derived from human embryonic kidney cells grown in tissue culture taken from a female fetus. HEK 293 cells have been widely used in cell biology research for many years, because of their reliable growth and propensity for transfection. They are also used by the biotechnology industry to produce therapeutic proteins and viruses Biosafety level 2 practices and containment facilities for all activities involving HEK-293 cell lines . Required PPE Procedures that may generate droplets (aerosols, splashes, sprays) with HEK-293 cell lines and their derivative should be handled in a Class II BSC with BSL-2 PPE (lab coat and gloves) (9) .

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. Microorganisms and Cell Cultures GmbH.

Biosafety Level 3 BSL-3 builds upon the containment requirements of BSL-2. If you work in a lab that is designated BSL-3, the microbes there can be either indigenous or exotic, and they can cause serious or potentially lethal disease through respiratory transmission. 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. CHO-ES Cells.

To reduce the risk of exposure or product contamination, cell 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 2020-10-14 · Biosafety Levels (BSL) Research and teaching activities involving infectious agents requires prior approval by the Institutional Biosafety Committee (IBC) via the Biohazard Use Authorization (BUA) review process. Each laboratory space where biohazardous materials are used is assigned one of 3 internationally recognized biosafety levels or BSL. vector to introduce potentially hazardous elements into the cells (e.g. oncogenes), they may not be sorted unless the cell-sorter is contained in a biological safety cabinet.

High Cell lines with endogenous biological agents or cells that have been deliberately infected Containment level appropriate to the agent. 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

The cell line has been distinguished as a separate sub-clone from the The biosafety level for this cell line is 2 where for CHO is only 1. Both are suitable for bioproduction. If your project is about a drug candidate I would recommend to use CHO because is more Sharma A, et al.

Regulation of technologies using recombinant DNA (rDNA) methods and organisms has eased considerably over the past 30 years. Most of the previous risk assessments focused on the possibility of a recombinant organism or its genetic element establishing itself in the environment if it escaped from a laboratory or cell culture or fermentation facility.

Contained use Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures GmbH 3. AAV/rAAV is propagated in insect cell lines . Determination of the biosafety level for AAV/rAAV meeting conditions 1 and 2 above and propagated in human cell lines will be made by the IBC on a case-by-case basis for each vector lot, when specific requirements have been addressed (see below “Exceptions to the requirement for BSL-2/ABSL-2”).
