Documentation
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.
Cells contain cytomegalovirus (CMV) DNA sequences
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.

Detailed product information
General
- Specific applications
-
This cell line was derived from the TF-1 cell line (ATCC CRL-2003).The cells can be used to access the potency and to study signal transduction of CNTF.
Characteristics

- Suspension
- Derivation
-
This cell line was derived from the TF-1 cell line (ATCC CRL-2003).Following transfection, a line of G418 resistant cells was obtained and named TF-1.CN5a.
- Age
- 35 years
- Ethnicity
- Asian
- Gender
- Male
- Expression markers
- Alpha subunit of human ciliary neurotrophic factor (CNTF) (receptor is not expressed by TF-1 cells)
- Comments
-
The cells stably express the alpha subunit of human ciliary neurotrophic factor (CNTF) receptor and CNTF supports the short term proliferation of the cells. Suggested assay conditions are washing the cells with RPMI to remove GM-CSF, then incubation in RPMI 1640 95%, fetal bovine serum 5%, and picogram/ml concentrations of CNTF. The cells maintain responsiveness for at least 193 population doublings in full maintenance medium.This cell line was derived from the TF-1 cell line (ATCC CRL-2003).TF-1 cells were transfected, using Transfectam, with the gene for the alpha subunit of human ciliary neurotrophic factor (CNTF) receptor ligated to the pCR3.1 vector.The vector contains cytomegalovirus (CMV) and SV40 viral sequences and the neomycin resistance gene.Following transfection, a line of G418 resistant cells was obtained and named TF-1.CN5a.TF-1.CN5a cells were grown, transiently, in the absence of GM-CSF and with 2 ng/ml CNTF to establish the TF-1.CN5a.1 cell line.The cells can be used to access the potency and to study signal transduction of CNTF.
Handling information
- Unpacking and storage instructions
-
- Check all containers for leakage or breakage.
- Remove the frozen cells from the dry ice packaging and immediately place the cells at a temperature below -130°C, preferably in liquid nitrogen vapor, until ready for use.
- Complete medium
- RPMI 1640 medium with 2 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate, 4.5 g/L glucose, 10 mM HEPES, and 1.0 mM sodium pyruvate supplemented with 2 ng/ml GM-CSF and 0.4 mg/ml G-418, 90%; fetal bovine serum, 10%
- Temperature
-
37°C
- Atmosphere
-
95% Air, 5% CO2
- Handling procedure
-
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.
- 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.
- It is recommended that the cryoprotective agent be removed immediately. Transfer the vial contents to a 15 mL centrifuge tube and dilute with the recommended complete culture medium centrifuge the cell suspension at approximately 125 x g for 5 to 10 minutes. Discard the supernatant and resuspend the cell pellet in an appropriate amount of fresh growth medium
- Transfer the cells to an appropriate size vessel. 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 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
-
Cultures can be maintained by addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 1 x 105 viable cells/mL. Maintain cell density at a cell concentration between 1 x 105 and 1 x 106 cells/mL.
Medium Renewal: Every 2 to 3 days
- Reagents for cryopreservation
- Complete growth medium supplemented with 5% (v/v) DMSO (ATCC 4-X)
