Derivation
151TAg (Polb/Pms-2 double null) is a mouse embryonic fibroblast (MEF) cell line derived from polymerase (DNA directed), beta (Polb)/ postmeiotic segregation increased 2 (S. cerevisiae (Pms2) double null embryos at day 14.5 of gestation. The Pms-2 deficient mice were constructed using ES-D3 [D3] embryonic stem cells [PubMed: 9096356]. The cells line was established by transfection with an expression vector for SV40 large T antigen. PubMed:8538772]. The cells are transgenic for lambda LIZ (Lac I/cII).

Complete Growth Medium The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Subculturing
Protocol:
  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
  3. Add 2.0 to 3.0 ml of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
    Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal.
  4. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
    An inoculum of 4 to 6 X 10(3) viable cells/cm2 is recommended.
  6. Incubate cultures at 37°C.
Interval: Maintain cultures at a cell concentration between 6 X 10(3) and 1 X 10(5) cells/cm2.
Subcultivation Ratio: A subcultivation ratio of 1:6 to 1:8 is recommended
Medium Renewal: Every two to three days
Cryopreservation
Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase
Culture Conditions
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37.0°C
Name of Depositor RW Sobol
Year of Origin 2000
