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.
NK-92 cells have the following characteristics: surface marker positive for CD2, CD7, CD11a, CD28, CD45, CD54 and CD56 bright; surface marker negative for CD1, CD3, CD4, CD5, CD8, CD10, CD14, CD16, CD19, CD20, CD23, CD34 and HLA-DR.
ATCC confirmed this cell line is positive for the presence of Epstein-Barr viral DNA sequences via PCR.
Cultures can be maintained by addition or replacement of medium. When replacing media, centrifuge cells and resuspend cell pellet in fresh medium at 2 to 3 X 105 viable cells/mL. These cells tend to grow in aggregates that may lose viability when they are dispersed. Accurate counts and viabilities may not be possible. Corning® T-75 flasks (catalog #431464) are recommended for subculturing this product.
