Melanocyte Growth Kit (ATCC® PCS-200-041)

Biosafety Level 1

Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.

Product Format frozen 1 Kit
Storage Conditions -20°C (or -70°C for long-term storage)

The Melanocyte Growth Kit contains components that when added to Dermal Cell Basal Medium (ATCC PCS-200-030) create a complete low-serum culture environment for melanocytes derived from normal human epidermis (e.g., Primary Epidermal Melanocytes, Normal, Human Neonatal, ATCC PCS-200-012). The complete low serum medium (less than 1.0% FBS) is formulated to support robust melanocyte growth in the absence of cholera toxin and phorbol 12-myristate 13-acetate (PMA). No feeder layers, extracellular matrix proteins or other substrares are required. The final concentration for each component in complete melainocyte growth medium is as follows:

  • rh Insulin: 5 µg/ml
  • Ascorbic Acid: 50 µg/ml
  • L-Glutamine: 6 mM
  • Epinephrine: 1.0 µM
  • Calcium chloride: 0.2 mM
  • M8 Supplement: Proprietary formulation
Complete Growth Medium
  1. Obtain one growth kit from the freezer; make sure that the caps of all components are tight.
  2. Thaw the components of the growth kit just prior to adding to the basal medium. It is necessary to warm the L-glutamine component in a 37°C water bath and shake to dissolve any precipitates, prior to adding to the basal medium.
  3. Obtain one bottle of Dermal Cell Basal Medium (485 mL) from cold storage.
  4.  Decontaminate the external surfaces of all growth kit component vials and the basal medium bottle by spraying with 70% ethanol.
  5. Using aseptic technique and working in a laminar flow hood or biosafety cabinet, transfer the indicated volume of each growth kit component to the bottle of basal medium using a separate sterile pipette for each.

  7. 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.
  8. Complete media should be stored in the dark at 2°C to 8°C (do not freeze). When stored under these conditions, complete media is stable for 30 days.
