Overview
A549 cells constituitvely expressing ACE2 and TMPRSS2. A sleeping beauty transposon system was used to generate this cell line which is highly susceptible to SARS-CoV-2.
Key elements and design rationale
- Model identity: A549 Cells Stably Expressing hACE2 Receptor and TMPRSS2 (A549-AT) is supplied as an engineered cell line derived from Human lung.
- Growth conditions: PriCoat™ T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) are recommended for optimal cell culture. Dulbecco's Modified Eagle Medium (DMEM), Low Glucose (TM501) + 10% FBS(Regular*) + 2 mM L-Glutamine (G275) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂. *Do not heat-inactivate
- Product format: Frozen, BSL-2
This cell-based model is generally used in cancer biology, phenotype comparison, and response profiling studies. Donor/background information is available for contextual interpretation.
Biological background
Therefore, the cell line is an excellent model for rapid and sensitive monitoring of SARS-CoV-2 infection and for screening host factors essential for viral replication. Donor/background information provided for this product: Male, 58, Caucasian, Lung carcinoma.
Research relevance and current trends
- Engineered cell lines are widely used for reporter-based readouts, perturbation studies, and assay optimization in reproducible culture systems.
- Reporter or transgene-bearing models are often compared with matched parental or control cells to interpret signal changes in context.
- Expression trends are typically evaluated alongside passage number, selection pressure, and baseline growth behavior.
Common research applications
- Cancer biology studies that compare proliferation-associated behavior, morphology, and pathway responses in vitro.
- Assay development for treatment response, reporter monitoring, or phenotype comparison under matched culture conditions.
- Side-by-side comparison of engineered versus parental background characteristics when relevant to the study design.
Changes in morphology, growth rate, viability, or reporter signal are typically interpreted together with passage history, culture matrix, and the specified growth conditions for the model.
Notes for experimental interpretation
- Morphology, doubling behavior, and reporter or marker output can shift with passage number, substrate choice, and medium composition; these variables should be recorded alongside experimental readouts.
- Matched controls such as parental cells, untreated cultures, or parallel cultures maintained under identical conditions help distinguish background effects from biology of interest.
Culture and product details
- Growth Conditions: PriCoat™ T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) are recommended for optimal cell culture. Dulbecco's Modified Eagle Medium (DMEM), Low Glucose (TM501) + 10% FBS(Regular*) + 2 mM L-Glutamine (G275) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂. *Do not heat-inactivate
- Split Ratio: 1:5 to 1:10
- Warranty: abm warrants that cell lines shall be viable upon initiation of culture for a period of thirty (30) days after shipment and that they shall meet the specifications on the applicable abm Material Product Information sheet, certificate of analysis, and/or catalog description. Such thirty (30) day period is referred to herein as the "Warranty Period”.
- Thaw cells quickly in a 37°C water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination.
- Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions.
- Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media. Centrifuge cells at 125xg for 5-7 minutes.
- Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask.
- Incubate the cells at the recommended conditions.
- Aspirate the culture media, and add 2-3ml of pre-warmed 0.25% Trypsin-EDTA to the culture vessel.
- Observe the cells under a microscope to confirm detachment (typically within 2-10 minutes). Cells that are difficult to detach can be put in 37°C, for several minutes to facilitate detachment.
- Neutralize Trypsin-EDTA by adding an equal volume of the complete growth media into the culture vessel.
- Transfer the culture suspension into a sterile centrifuge tube, and centrifuge at 125xg for 5 minutes. The actual centrifuge duration and speed may vary depending on the cell type.
- Aspirate the supernatant, and re-suspend the pellet with pre-warmed fresh complete growth media. Add appropriate aliquots of the cell suspension to new culture vessels, as desired.
- Incubate the cells at the recommended conditions.

How many times can cells divide?
Primary cells have a limited lifespan and will undergo a finite number of population doublings before entering senescence. The exact number varies by cell type and culture conditions.
Immortalized cell lines are capable of extended or indefinite proliferation under proper culture conditions, although growth characteristics may vary between lines.
Do I need Applied Cell Extracellular Matrix (G422) if I am using PriCoat™ flasks?
