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
As with other mammalian cell lines, when working with CHO DG44 Cells (cGMP banked), handle them as potentially biohazardous material under at least Biosafety Level 1 containment.
A biosafety level (BSL), or pathogen/protection level, is a set of biocontainment precautions required to isolate dangerous biological agents in an enclosed laboratory facility. The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4). 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.
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.

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

Chinese Hamster Ovary (CHO) cells are among the most commonly used cell lines for transfection, expression and large-scale production of recombinant proteins. The CHO-S cell line is a stable aneuploid cell line established from the ovary of an adult Chinese hamster (Puck, 1958). The cell line has been distinguished as a separate sub-clone from the

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.
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. Biosafety Level 2 (BSL 2): builds upon BSL-1.

used for mammalian cell gene transfer in the absence of replication within the transduced cells. For baculovirus 168 mediated gene transfer into mammalian cells, the term transduction is used rather than infection due to the inherent inability of the virus to replicate in mammal, ian cells. From a biosafety standpoint this is a highly Biosafety Levels: Breaking the Chain Another way to think about biosafety levels is that they are a systematic approach to disrupting the chain of infection (or release).
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 Control the cell morphology and confluency under the microscope. Incubate at 37°C for a minimum of 24 hrs. Spin down the collected medium at 300x g for 3 minutes to collect the cells which may have detached during transit. If a cell pellet is visible, resuspend the cells in 5 ml of cell culture medium and transfer to 1xT25 cell culture.
