Can I mix the SkMC Supplement with the Skeletal Muscle Cell Basal Medium and freeze some down for later use? If so how long can it remain frozen?

The PromoCell Basal Media must be stored between 4-8°C and should not be frozen; as this can lead to precipitations. The same is true after addition of the supplements: the complete medium has to be kept at 4-8°C. If you prefer to make up smaller volumes of complete medium; you can aliquot the Supplement Mix and refreeze those aliquots at -20°C until use. This way you can extend the period in which you can use the supplemented media.
