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.
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.

- Gender
- Female
- Karyotype
- This is a near diploid line. The modal chromosome number is 47 occurring at 38%, and the rate of polyploidy is 9%. Fifteen to sixteen marker chromosomes are present in all cells. They are t(1,?), t(3p,5q), der(3)t(?q29;?), t(3q,?), 5q+, i(6p), t(7q,?), 9q+, t(10q,21q), 16q+ and five to six others. Normal chromosomes 3, 10, 13 and 16 are absent. There are two copies of the X chromosome. No Y chromosomes were detected in QM stained preparations

ES-D, 1G6PD, BGLO-I, 2Me-2, 1PGM1, 1PGM3, 0
- Comments
-
The cells survive culturing in Difco Bacto-Agar but do not form colonies.Scanning electron microscopy reveals some variation in the number and frequency of surface blebs, lamellipodia and microvilli.The line is of interest in studies of cell differentiation, animal models of tumor therapy and biochemical evaluations.
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
- 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: fetal bovine serum (ATCC 30-2020) to a final concentration of 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.
- Transfer the vial contents to a 75 cm2 tissue culture flask and dilute with the recommended complete culture medium (see the specific batch information for the recommended dilution ratio). 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.
If it is desired that the cryoprotective agent be removed immediately, or that a more concentrated cell suspension be obtained, centrifuge the cell suspension at approximately 125 xg for 5 to 10 minutes. Discard the supernatant and resuspend the cells with fresh growth medium at the dilution ratio recommended in the specific batch information.
- 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 in fresh medium at 2 - 3 X 105 viable cells/mL. Maintain cell density between 1 X 105 and 1 to 2 X 106 viable cells/mL.Medium Renewal: Every 3 to 4 days
- Reagents for cryopreservation
- Complete growth medium supplemented with 5% (v/v) DMSO (ATCC 4-X)
