Is PromoCell Keratinocyte Growth Medium 2 suitable for the growth of primary mouse keratinocytes?

Yes. PromoCell Keratinocyte Growth Medium 2 (C-20011) can be used to culture primary mouse keratinocytes, provided that the calcium concentration is adjusted.
 
Calcium requirements

• For primary mouse keratinocytes, the CaCl₂ concentration should be reduced to 0.025-0.05 mM.
• By comparison, the optimal calcium concentration for primary human keratinocytes is 0.06 mM.

Keratinocyte Growth Medium 2 is supplied with CaCl₂ in a separate tube, allowing the calcium concentration to be easily adjusted to meet the requirements of various keratinocyte culture systems.
