NCI-H23 Cell Line

General Information
Organism Homo sapiens, human
Cell Line Description NCI-H23 is a human non-small cell lung cancer (NSCLC) cell line derived from a primary lung adenocarcinoma specimen obtained from a 51-year-old Black male patient. The cell line exhibits epithelial morphology and grows as an adherent monolayer under standard culture conditions. Cytogenetically, it displays an aneuploid karyotype characterized by numerical and structural chromosomal abnormalities. At the molecular level, NCI-H23 harbors key oncogenic driver mutations commonly found in aggressive NSCLC, including mutations in the KRAS (G12C) and TP53 genes, as well as inactivation of the LKB1/STK11 gene. Due to its well-defined genomic profile and robust growth characteristics, NCI-H23 has become a widely recognized in vitro model for investigating the pathogenesis of lung adenocarcinoma, exploring KRAS G12C signaling dynamics, evaluating novel targeted therapies and chemotherapeutic agents, and conducting high-throughput functional genomic screens.

Culture Conditions and Handling
Subculturing 1. Remove and discard the culture medium.
2. Briefly rinse the cell monolayer with PBS (without Ca2+/Mg2+) to completely remove residual serum.
3. Add 1.0 to 2.0 mL of 0.25% trypsin-0.03% EDTA solution and incubate at 37°C until the cell monolayer detaches (typically 2 to 5 minutes).
4. Add fresh complete growth medium to neutralize the trypsin and gently pipette up and down to prepare a single-cell suspension.
5. Subculture the cell suspension into new culture vessels.
Medium Renewal Every 2 to 3 days
Subcultivation Ratio A split ratio of 1:3 to 1:6 is recommended
Culture Conditions Atmosphere: Air, 95%; CO2, 5%; Temperature: 37°C
Cryopreservation Complete growth medium supplemented with 5% to 10% (v/v) DMSO
