Strain C57BL/6
Applications
Coat-color chimera production was high using c2J blastocysts while FVB blastocysts produced a low number of chimeras [PubMed: 11730008].
The clonal embryonic stem cell line #693 ES C57BL/6 was derived from a strain C57BL/6J (B6) mouse blastocyst [PubMed: 11730008].
The ES cells were shown to populate the germ line of two host blastocyst donors, FVB/NJ (FVB) and the coisogenic strain C57BL/6-Tyrc-2J (c2J).
Storage Conditions Liquid nitrogen vapor phase
Derivation
The clonal embryonic stem cell line #693 ES C57BL/6 was derived from a strain C57BL/6J (B6) mouse blastocyst RefSchuster-Gossler K, et al. Use of coisogenic host blastocysts for efficient establishment of germline chimeras with C57BL/6J ES cell lines. BioTechniques 31: 1022-1024, 1026, 2001. PubMed: 11730008
Clinical Data
The ES cells were shown to populate the germ line of two host blastocyst donors, FVB/NJ (FVB) and the coisogenic strain C57BL/6-Tyrc-2J (c2J).

Complete Growth Medium Grow ES cells in Mouse ES Cell Basal Medium (ATCC SCRR-2011) that has been supplemented with the following components:
1. 0.1 mM 2-mercaptoethanol (Life Technologies Cat. No. 21985-023)
2. 1,000 U/mL mouse leukemia inhibitory factor (LIF) (Millipore Cat. No. ESG1107)
3. 10% to 15% ES-Cell Qualified FBS (ATCC® SCRR-30-2020) or an ES cell qualified serum replacement
Complete Growth Medium for Mouse ES Cells is stable for 14 days when stored at 2°C to 8°C.
Subculturing
Feeder Cell Preparation for Subcultures
  1. Daily maintain a sufficient number of flasks that have been pre-plated with MEFs in complete medium for feeder cells.
  2. One hour before subculturing the ES cells, perform a 100% medium change for the MEFs using complete growth medium for ES cells.
Dissociation and Transfer of ES Cells
  1. Aspirate the medium from the flask(s) containing ES cells.
  2. Wash with PBS Ca+2/Mg+2-free (ATCC® SCRR-2201).
  3. Add 3.0 mL of 0.25% (w/v) Trypsin / 0.53 mM EDTA solution (ATCC® 30-2101) and place in incubator. After about one minute the ES colonies will dissociate and all cells will detach from the flask.
  4. Dislodge the cells by gently tapping the side of the flask then wash the cells off with 7-10 mL of fresh culture medium. Triturate cells several times with a 10 mL pipette in order to dissociate the cells into a single-cell suspension.
  5. Spin the cells at 270 x g for 5 min. Aspirate the supernatant.
  6. Resuspend in enough complete growth medium for ES cells to reseed new vessels at the desired split ratio (i.e. a split ratio of 1:4 to 1:7 is recommended). Perform a cell count to determine the total number of cells. ES cells should be plated at a density of 30,000 - 50,000 cells/ cm2.
  7. Add separate aliquots of the cell suspension to the appropriate size flask containing feeder cells and add an appropriate volume of fresh complete growth medium for ES cells to each vessel.
  8. Incubate the culture at 37°C in a humidified 5% CO2/95% air incubator. Perform a 100% medium change every day, passage cells every 1-2 days.
Interval: Every one to two days
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:7 is recommended
Medium Renewal: Every day
Cryopreservation
Liquid nitrogen vapor phase
Culture Conditions
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
