FAQS:

• 
  
  • Q. WHY IS THE MEGACULT™-C FORMULATION SERUM FREE?
    A. MegaCult™-C is formulated without FBS to avoid inhibition of CFU-Mk growth by TGF beta and Platelet Factor-4, which are often present in the serum.
  • Q. WHY USE SEMI-SOLID MEDIA?
    A. Semi-solid media (such as methylcellulose-based or collagen-based) allow the clonal progeny of a single progenitor cell to stay together so you can recognize distinct colonies.
