Summary description:

This protocol may be used to prepare mouse ES cells for karyotyping.

Reagents. supplies, and equipment:

  • cES cell media
  • 60 mm tissue culture dish with MEFs

Procedure:

  1. Please notify the TMESCSR that you have mES cells that you would like to have karyotyped. The Resource will schedule and coordinate a time for cells to be delivered for karyotyping.
  2. E-mail the names and clone numbers of the cell lines requested for karyotyping to Jake Stein (jake.stein@vanderbilt.edu) and Jennifer Skelton (jennifer.skelton@vanderbilt.edu).  Label the culture dishes with the same names.
  3. On a 60 mm culture dish, plate cells on a layer of MEFs.
  4. Colonies need to be at least medium in size and 50% to 90% confluent for karyotyping.  This is usually about two days of growth.
  5. On the day dishes are being handed off to the TMESCSR for karyotyping, feed the plate(s) with cES before 10:00 AM and communicate to the TMESCSR personnel what time they were fed.
  6. Bring plates for karyotyping to the TMESCSR in 9410 MRB IV by 11:30 AM.
