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).

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.

The cells can be used in adherence assays as a target cell for malaria infected erythrocytes. 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 hamster1. The cell line has been distinguished as a separate sub-clone from the common 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.

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
