| Addtional Info | NCI-N87 cells express the surface glycoproteins carcinoembryonic antigen (CEA) and TAG 72, and are L-dopa decarboxylase (DDC) negative. They were minimally positive for vasoactive intestinal peptide (VIP) receptors and lacked gastrin receptors. They were found to express receptors for muscarinic cholinergic agents. No evidence of amplification or rearrangements was noted with the N-myc, L-myc, myb and EGF receptor genes. The cell line expressed levels of c-myc and c-erb-B 2 RNA that were comparable to other cell lines.There was no expression of the following genes: N-myc, L-myc, c-cis, IGF-2, or gastrin releasing peptide. NCI-N87 cells have a reported plating efficiency of 4.3%. |
| Culture Medium | RPMI-1640 medium modified to contain 2 mM L-glutamine, 4500 mg/L glucose with fetal bovine serum to a final concentration of 10%. |
| Subculturing | Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes. Remove and discard culture medium. Briefly rinse the cell layer with PBS without calcium and magnesium to remove all traces of serum that contains trypsin inhibitor. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes). Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting. Add appropriate aliquots of the cell suspension to new culture vessels. Incubate cultures at 37°C. Population Doubling Time: 47 hrs NOTE: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 12 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 6th edition, published by Alan R. Liss, N.Y., 2010. |
| Subculturing Medium Renewal | Two to three times weekly |
| Subculturing Subcultivation Ratio | 1:3 to 1:4 is recommended |
| Culture Conditions | Atmosphere: air, 95%; carbon dioxide (CO2), 5% Temperature: 37°C |
| Cryopreservation | 95% FBS + 5% DMSO (Dimethyl sulfoxide) |
| Thawing Frozen Cells | SAFETY PRECAUTION:
It is strongly recommended to always wear protective gloves, clothing, and a full-face mask when handling frozen vials. Some vials may leak when submerged in liquid nitrogen, allowing nitrogen to slowly enter the vial. Upon thawing, the conversion of liquid nitrogen back to its gas phase may cause the vial to explode or eject its cap with significant force, creating flying debris.
NOTE: It is important to avoid excessive alkalinity of the medium during cell recovery. To minimize this risk, it is recommended to place the culture vessel containing the growth medium in the incubator for at least 15 minutes before adding the vial contents. This allows the medium to stabilize at its normal pH (7.0 to 7.6). |

Gazdar and associates at the National Cancer Institute from a liver metastasis of a well differentiated carcinoma of the stomach taken prior to cytotoxic therapy. The tumor was passaged as a xenograft in athymic nude mice for three passages before the cell line was established. |
