Product sheet

Technical data sheet

BSL 2

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

General

Specific applications: Enabling sensitive and quantitative assessment of signal transduction makes this reporter cell line ideal for high throughput in vitro bioluminescence assays to study signaling pathways and the development of new checkpoint inhibitors for immuno-oncology drug discovery.

Characteristics

Cells per vial: ≥ 1.0 x 10⁶
Growth properties: Adherent
Age: embryo
Antigen expression: PD-L1 and SIRPA verified at ATCC
Comments: HMC3 NFκB-LUC2 luciferase reporter cell line was derived from parental HMC3 (ATCC CRL-3304) cell line by stably expressing firefly luciferase gene (luc2) under control of the nuclear factor kappa B (NFκB) promoter. This cell line was established through lentiviral transduction and single cell cloning. The cells, upon stimulation, express high levels of enzymatically active luciferase protein, which can be detected via in vitro bioluminescence assays. This reporter cell line is useful for monitoring the activity of tumor necrosis factor alpha (TNF-α)-induced signal transduction pathways.

Handling information

Complete medium

The base medium for this cell line is ATCC®-formulated Eagle’s Minimum Essential Medium (ATCC 30-2003). To make the complete growth medium, add the following components to the base medium: fetal bovine serum (FBS; ATCC 30-2020) to a final concentration of 10% and puromycin to a final concentration of 1.0 µg/mL.

Temperature

37°C

Atmosphere

95% Air, 5% CO₂

Handling procedure

To ensure the highest level of viability, thaw the vial and initiate the culture as soon as possible upon receipt. If upon arrival, continued storage of the frozen culture is necessary, it should be stored in liquid nitrogen vapor phase and not at -70°C. Storage at -70°C will result in loss of viability.

Thaw the vial by gentle agitation in a 37°C water bath. To reduce the possibility of contamination, keep the O-ring and cap out of the water. Thawing should be rapid (approximately 2 minutes).
Remove the vial from the water bath as soon as the contents are thawed and decontaminate by dipping in or spraying with 70% ethanol. All of the operations from this point on should be carried out under strict aseptic conditions.
Resuspend cell pellet with the recommended complete medium (see the specific batch information for the culture recommended dilution ratio) and dispense into a 25 cm² or a 75 cm² culture flask. It is important to avoid excessive alkalinity of the medium during recovery of the cells. It is suggested that, prior to the addition of the vial contents, the culture vessel containing the complete growth medium be placed into the incubator for at least 15 minutes to allow the medium to reach its normal pH (7.0 to 7.6)
Incubate the culture at 37°C in a suitable incubator. A 5% CO₂ in air atmosphere is recommended if using the medium described on this product sheet.

Subculturing procedure

Volumes used in this protocol are for 75 cm ² flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. Corning® T-75 flasks (catalog #431464) are recommended for subculturing this product.

1. Remove and discard culture medium.

2. Briefly rinse the cell layer with Dulbecco's Phosphate Buffered Saline (D-PBS; ATCC 30-2200) to remove all traces of serum that contains trypsin inhibitor.

3. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).

Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37 °C to facilitate dispersal. .

4. Add 6.0 to 8.0 mL complete growth medium and aspirate the cells by gentle pipetting.

5. Add appropriate aliquots of the cell suspension to new culture vessels. Cultures can be established at 1-4 X 10⁴ viable cells/cm². Do not exceed 7x10⁴ viable cells/cm².

6. Incubate cultures at 37 °C. .

Interval: Maintain the cell density from 1 X 10⁴ to 2 X 10⁵ cells/cm2. Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:8 is recommended. Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density).
