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.

Detailed product information


Specific applications

Transfection Host:  These cells may be used for stable transfection studies.


Growth properties
DT40 is an avian leukosis virus (ALV) induced bursal lymphoma cell line derived from a Hyline SC chicken.
The original lymphoma was induced by viral infection of a 1 day old chicken with Rous associated virus 1 (RAV-1).
Cell suspensions prepared from tumors that developed within the bursa of Fabricus were transferred intravenously into young syngeneic recipient chickens.
After one transfer in vivo, the DT40 cell line was established.
1 day
Yes, in 2 day old syngeneic chickens; tumors were observed in the spleens, kidneys and livers of recipient animals
Genes expressed
immunoglobulin, IgM (surface)
The cell line contains proviral DNA sequences integrated upstream from the c-myc proto-oncogene and expresses increased levels of c-myc RNA.

It lacks a normal c-myc gene, but contains two copies of an ALV deregulated myc gene.

The cells retain the ability to rearrange the immunoglobulin light chain gene (IgL).

At the IgL locus, DT40 contains one rearranged and one germline allele.

The cell line exhibits a lymphoblastoid phenotype.

Infectivity assays revealed that DT40 releases low levels of infectious RAV-1.

Both the c-rel gene and the v-rel oncogenes induce major histocompatibility (MHC) class II antigen expression on the DT40 cell line. 

The expression of MHC class II is induced more rapidly by v-rel than c-rel and several weeks after infection, rel induced class II antigen as much as 50 fold more efficiently than c-rel. 

Handling information

Unpacking and storage instructions
  1. Check all containers for leakage or breakage.
  2. 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
Dulbecco's modified Eagle's medium with 4 mM L-glutamine modified to contain 4.5 g/L glucose, 1.5 g/L sodium bicarbonate and 0.05 mM 2-mercaptoethanol, 75%; tryptose phosphate broth, 10%; fetal bovine serum, 10%; chicken serum, 5%
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.

  1. 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).
  2. 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.
  3. It is recommended that the cryoprotective agent be removed immediately.  Centrifuge the cell suspension at approximately 125 xg for 5 to 10 minutes.  Discard the supernatant and resuspend the cell pellet in an appropriate amount of fresh growth medium. 
  4. Transfer the cell pellet 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).
  5. 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 or replacement of fresh medium. Start cultures at 3 x 105 cells/mL and maintain between 2 x 105 and 2 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)
