| Derivation | NK-92® MI is an interleukin-2 (IL-2) independent Natural Killer Cell line derived from the NK-92® (ATCC CRL-2407) cell line by transfection. 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. The parental cells were transfected with human IL-2 cDNA in the retroviral MFG-hIL-2 vector by particle-mediated gene transfer. The transfection is stable. |

| Comments | NK-92® and this derivative cell line NK-92® MI 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.
The parental IL-2 dependent cell line is available as ATCC CRL-2407 (NK-92® ). NK-92® MI was shown to contain, express, and synthesize the hIL-2. A culture submitted to the ATCC in September of 1998 was found to be contaminated with mycoplasma. Progeny were cured by a 21-day treatment with BM Cycline. The cells were assayed for mycoplasma, by the Hoechst stain, PCR and the standard culture test, after a six-week period following treatment. All tests were negative. 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; horse serum to a final concentration of 12.5%; fetal bovine serum to a final concentration of 12.5%.

| Subculturing | Cultures can be maintained by centrifuging cells and resuspending cell pellet in fresh medium at 2 - 3 x 105 viable cells/mL. Centrifugation and full replacement of culture medium may be performed for the first subcultures. Cultures can then be maintained by addition of fresh medium. These cells tend to grow in aggregates that may lose viability when they are dispersed. Accurate counts and viabilities may not be possible. Maintain cell density between 2 x 105 and 1 x 106 viable cells/mL or use a 1:3 spilt ratio. |
