Complete Growth Medium
|
- Obtain one Mesenchymal Stem Cell Growth Kit–Low serum from the freezer; make sure that the caps of all components are tight.
- Thaw the components of the growth kit just prior to adding them to the basal medium.
- Obtain one bottle of Mesenchymal Stem Cell Basal Medium (485 mL) from cold storage.
- Decontaminate the external surfaces of all growth kit component vials and the basal medium bottle by spraying them with 70% ethanol.
- Using aseptic technique and working in a laminar flow hood or biosafety cabinet, transfer the indicated volume of each growth kit component, as indicated in Table 1, to the bottle of basal medium using a separate sterile pipette for each transfer.

- Tightly cap the bottle of complete growth medium and swirl the contents gently to assure a homogeneous solution. Do not shake forcefully to avoid foaming. Label and date the bottle.
- Complete growth media should be stored in the dark at 2°C to 8°C (do not freeze). When stored under these conditions, complete growth media is stable for two weeks.
