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.
Enabling sensitive and quantitative assessment of signal transduction makes this reporter cell line ideal for in vitro bioluminescence assays to study signaling pathways, development of new drugs, and safety evaluation of new chemicals and drugs.
THP-1 cell line (ATCC TIB-202) is commonly used to study monocyte and macrophage activities, functions, innate immune mechanisms and signaling pathways. This luciferase reporter cell line was derived from parental line TIB-202 by stably expressing firefly luciferase gene (luc2) under control of an interferon-sensitive response element (ISRE) 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 interferon-induced signal transduction pathways.
The base medium for this cell line is ATCC-formulated RPMI-1640 Medium (ATCC 30-2001). To make the complete growth medium, add the following components to the base medium:
To insure 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.
Cultures can be maintained by addition or replacement of fresh medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 2 to 4 X 105 viable cells/mL. Subculture when cell concentration reaches 8 X 105 cells/mL. Do not allow the cell concentration to exceed 1 X 106 cells/mL. Corning® T-75 flasks (catalog #431464) are recommended for subculturing this product.
Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density).
Complete growth medium supplemented with 5% (v/v) DMSO (ATCC 4-X)
Luciferase assay: ≥ 10-fold increase in activity, basal to stimulation
The product is provided 'AS IS' and the viability of ATCC® products is warranted for 30 days from the date of shipment, provided that the customer has stored and handled the product according to the information included on the product information sheet, website, and Certificate of Analysis. For living cultures, ATCC lists the media formulation and reagents that have been found to be effective for the product. While other unspecified media and reagents may also produce satisfactory results, a change in the ATCC and/or depositor-recommended protocols may affect the recovery, growth, and/or function of the product. If an alternative medium formulation or reagent is used, the ATCC warranty for viability is no longer valid.
