A-427 Luciferase Reporter Cell Line

Frequently Asked Questions

• What is the A-427 Luciferase Reporter Cell Line?

  The A-427 Luciferase Reporter Cell Line is generated from the A-427 cell line, originally isolated from a human lung carcinoma. This cell line has been genetically engineered to constitutively express the luciferase gene, making it useful for real-time monitoring of cell behavior and drug responses using bioluminescent imaging, particularly in studies related to lung cancer.

• What is the recommended culture medium for the A-427 Luciferase Reporter Cell Line?

  The A-427 Luciferase Reporter Cell Line should be cultured in RPMI 1640 medium supplemented with 10% fetal bovine serum (FBS) and 1% penicillin-streptomycin. To maintain selective pressure and ensure stable expression of luciferase, 0.5 µg/mL puromycin can be added to the culture medium.

• What are the thawing procedures for the A-427 Luciferase Reporter Cell Line?

  Upon receipt, thaw the cryovials in a 37°C water bath quickly to minimize exposure time, ensuring that the vial stays above the water to prevent contamination. After thawing, wipe the vial with 70% ethanol, transfer the contents to a centrifuge tube containing 5 mL of complete culture medium, centrifuge at 200×g for 5-10 minutes, and discard the supernatant. Resuspend the cells in fresh medium and transfer them to a new culture flask.

• What are the applications of the A-427 Luciferase Reporter Cell Line?

  This cell line is primarily used for researching lung cancer mechanisms and drug screening, benefiting from the luciferase gene for easy tracking of tumor dynamics in live animal models and in vitro systems. It enables researchers to perform non-invasive imaging to assess tumor growth, metastasis, and response to therapeutics.

• What safety precautions should be taken when handling this cell line?

  Handling of the A-427 Luciferase Reporter Cell Line should adhere to Biosafety Level 1 (BSL-1). Appropriate personal protective equipment should be worn, and procedures should be conducted in a biosafety cabinet. The cell line is intended for research use only and not for therapeutic or diagnostic applications in humans or animals. Proper biocontainment and disposal protocols should be followed to ensure environmental and personal safety.
