Comments Rap1 exon 2 is flanked by two loxP sequences; one FRT sequence remains. Inducible Rap1 knockout can be achieved by transduction of Cre recombinase to the MEFs. This inducible Rap1 knockout MEF line is useful in studies of telomere biology.

Complete Growth Medium

The base medium for this cell line is DMEM (ATCC® 30-2002™). To make the complete medium add the following components to 500 mL of the base medium:

  • 56 mL fetal bovine serum (FBS; ATCC® 30-2020™) for a final concentration of 10%
  • 5.6 mL L-glutamine (200 mM; ATCC® 30-2214™) for a final concentration of 2 mM
  • 5.6 mL NEAA (Nonessential Amino Acids, 100X; Gibco cat# 11140050) for a final concentration of 0.1 mM
Subculturing
Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. Corning® T-75 flasks (catalog #430641) are recommended for subculturing this product.
  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.
    Cultures can be established between 1x 104 and 1.5 x 105 viable cells/cm2.
  6. Incubate cultures at 37°C.
Interval: Maintain cultures at a cell concentration between 1 X 104 and 1.5  X 105 cell/cm2.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:8 is recommended
Medium Renewal: 2 to 3 times per week
