| Clinical Data： | 51 years Black male This line was derived from a lung cancer obtained from a patient prior to therapy. |
| Oncogene： | myc +; src +; abl +; erb +; ras +; sis - |
| Genes Expressed： | myc +; src +; abl +; erb +; ras +; sis - |
| Comments： | The cells carry the K-ras 12 mutation, and there is a mutation in codon 246 (ATC -> ATG, isoleucine -> methionine) of the p53 gene.
There is expression of C-myc, L-myc, v-src, v-abl, v-erb B, c-raf 1, Ha-ras, Ki-ras and N-ras RNAs.
The cells express heterogeneous mRNA expression for PDGF A and B chain, transforming growth factor alpha and beta and the epidermal growth factor receptor (EGFR).
NCI-H23 exhibits a high degree of c-myc DNA amplification (20-fold) but no detectable amplification of c-myc RNA.
The cells stain positive for keratins 5+8 and 18 and vimentin but are negative for neurofilament.
NCI-H23 cells are L-dopa decarboxylase-negative.
They have a reported colony forming efficiency of 9.7% in soft agarose.

| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, ATCC 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (ATCC 30-2020) to a final concentration of 10%.
|
| Subculturing： | Remove spent medium, and add fresh 0.25% trypsin, 0.03% EDTA solution for 2 to 3 minutes at room temperature. Remove the trypsin and incubate the flask at 37°C for 5 to 10 minutes or until the cells detach. Add fresh medium, aspirate and dispense into new flasks. Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:6 is recommended
Medium Renewal: Every 2 to 3 days |
