suspension, multicell aggregates |
Biosafety Level |
2
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. |
Disease |
malignant non-Hodgkin's lymphoma |
Age |
50 years |
Gender |
male |
Ethnicity |
Caucasian |
Applications |
This cell line is a suitable transfection host.
The cell line is cytotoxic to a wide range of malignant cells; it kills both K562 cells and Daudi cells in chromium release assays.
NK-92 cells (after irradiation to prevent proliferation) can be used effectively for immunological ex vivo purging of leukemia from blood without compromising hematopoietic cell function. |
Storage Conditions |
liquid nitrogen vapor phase |

Derivation |
NK-92 is an interleukin-2 (IL-2) dependent Natural Killer Cell line derived from peripheral blood mononuclear cells from a 50 year old Caucasian male with rapidly progressive non-Hodgkin's lymphoma. |
Clinical Data |

Antigen Expression |
CD2 +, CD7 +, CD11a +, CD28 + , CD45 +, CD54 +, CD56 +, CD1 -, CD3 -, CD4 -, CD5 -, CD8 -, CD10 -, CD14 -, CD16 -, CD19 -, CD20 -, CD23 -, CD34 -, HLA-DR - |
Comments |
The cell line is dependent on the presence of recombinant Il-2 and a dose as low as 10 U/mL is sufficient to maintain proliferation; cells will die within 72 hours in the absence of IL-2.
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. |
Complete Growth Medium |
The base medium for this cell line is Alpha Minimum Essential medium without ribonucleosides and deoxyribonucleosides but with 2 mM L-glutamine and 1.5 g/L sodium bicarbonate . To make the complete growth medium, add the following components to the base medium: 0.2 mM inositol; 0.1 mM 2-mercaptoethanol; 0.02 mM folic acid; 100-200 U/ml recombinant IL-2; adjust to a final concentration of 12.5% horse serum and 12.5% fetal bovine serum.

Subculturing |
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.
NK-92 cells are extremely sensitive to overgrowth and media exhaustion.
Medium Renewal: Replace with fresh medium every 2 to 3 days (depending on cell density)
Note: Successful growth of this cell line is very dependent upon the quality of IL-2 used in the growth medium. ATCC recommends using the highest quality IL-2 available.
