NCI-H522

The NCI-H522 cell line is derived from a human non-small cell lung carcinoma (NSCLC), specifically an adenocarcinoma, of an adult patient. This cell line is extensively used in lung cancer research, offering a model to study the molecular and cellular mechanisms underlying adenocarcinoma, the most common subtype of NSCLC. NCI-H522 cells are valuable for investigating genetic mutations, signal transduction pathways, and therapeutic responses associated with lung adenocarcinoma.

NCI-H522 cells exhibit an epithelial morphology and express markers characteristic of lung adenocarcinoma, including cytokeratins and carcinoembryonic antigen (CEA). They harbor genetic alterations frequently observed in NSCLC, such as mutations in the TP53 gene and deletions in the RB1 gene. Researchers utilize NCI-H522 cells to explore key signaling pathways involved in lung cancer progression, such as the EGFR, KRAS, and PI3K/Akt pathways. These cells are also employed in high-throughput drug screening assays and preclinical testing of chemotherapeutic agents, targeted therapies, and immunotherapies. Additionally, NCI-H522 cells are used to study mechanisms of drug resistance and to develop strategies to overcome it. The relevance of the NCI-H522 cell line in lung adenocarcinoma research highlights its importance in advancing our understanding of lung cancer biology and in the development of new and more effective treatment approaches for patients with NSCLC.

37°C, 5% CO₂, humidified atmosphere.

1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods.

To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.

For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen.

Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage.

At Cytion, we stand behind the quality and viability of our products. We guarantee that our cells will be viable at the start of culture for 60 days after shipment from our facilities. We assure that all materials conform to the specifications described in the Certificate of Analysis and/or Product Sheet.
