cell substrate contains potential contaminating agents from a tumor-derived cell line, to detect very low levels of and/or unknown viral contamination , to detect non-cultivable viruses, or to identify the species of the contaminant. Biosafety testing can be more effective and thorough by use of NGS and bioinformatics. 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.

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 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. 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 Material Safety Data Sheet for Cell Cultures (Biosafety Level 1) 1.

For most cell lines the appropriate level of containment is Level 2 requiring a class 2 microbiological safety cabinet. However, this may need to be increased to containment Level 3 depending upon the type of manipulations to be carried out and whether large culture volumes are envisaged.
