Complete Differentiation Medium: Primary Skeletal Differentiation Tool (ATCC PCS-950-050); a standalone media with no additional supplements required.

Culture Conditions
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37°C
  1. Passage normal skeletal muscle cells when culture has reached approximately 80% to 90% confluence, and are actively proliferating.
  2. Warm both the Trypsin-EDTA for Primary Cells (ATCC® PCS-999-003) and the Trypsin Neutralizing Solution (ATCC® PCS-999-004) to room temperature prior to dissociation. Warm complete growth medium to 37°C prior to use with the cells.
  3. For each flask, carefully aspirate the spent media without disturbing the monolayer.
  4. Briefly rinse the cell layer with 3 to 5 mL DPBS (ATCC® 30-2200) to remove residual traces of serum and then aspirate and discard the DPBS.
  5. Add pre-warmed trypsin-EDTA solution (2 to 3 mL for every 25 cm2) to each flask.
  6. Gently rock each flask to ensure complete coverage of the trypsin-EDTA solution over the cells.
  7. Observe the cells under the microscope. When the cells pull away from each other and round up (typically within 3 to 5 minutes), remove the flask from the microscope and gently tap it from several sides to promote detachment of the cells from the flask surface.
  8. When the majority of cells are detached, quickly add an equal volume of Trypsin Neutralizing Solution (ATCC® PCS-999-004) to each flask. Gently pipette or swirl the culture to ensure all of the trypsin-EDTA solution has been neutralized.
  9. Transfer the dissociated cells to a sterile centrifuge tube and set aside while processing any remaining cells in the flask.
  10. Add 3 to 5 mL Trypsin Neutralizing Solution to the flask to collect any remaining dissociated cells. Transfer remaining cells into the centrifuge tube.
  11. Repeat steps 10 as needed until all cells have been collected from the flask.
  12. Centrifuge the cells at 150 x g for 3 to 5 minutes.
  13. Carefully aspirate the neutralized dissociation solution from the cell pellet and re-suspend the cells in 5 to 8 mL fresh, pre-warmed, complete growth medium.
  14. Count the cells and seed new flasks at a density of 2,500 to 5,000 cells per cm2.
  15. Place freshly seeded flasks in a 37°C, 5% CO2 incubator for at least 24 to 48 hours before processing the cells further. Refer to Maintenance for guidelines on feeding.
