StemFit® Basic02 by Ajinomoto: iPS/ES Cell Culture Medium

High-Performance iPS / ES Cell Culture Medium for Basic Research

 StemFit®Basic02 is a xeno-free, defined medium for human pluripotent stem cell culture. This medium is capable of reprogramming, maintaining and differentiating human iPS and ES cells under feeder-free culture conditions.


  • Xeno-free formulation
  • Enabling single cell cloning
  • Providing high colony forming efficiency
  • Weekend-free feeding
  • Achieving high cost-performance

Media preparation

StemFit®Basic02 is provided frozen as a 2 component set containing “Liquid A” and “Liquid B” and can be stored at below -20 °C until use. Use sterile techniques to prepare StemFit®Basic02 medium.

  1. Before use, thaw the frozen medium supplements at room temperature or overnight at 2-8 °C. Do not thaw the frozen supplements at 37 °C, as it accelerates the degradation of medium ingredients.
  2. Aseptically mix medium components by adding the full volume of “Liquid B” to “Liquid A”. Mix thoroughly. If prepared aseptically, StemFit®Basic02 is ready for use.
  3. Upon thawing, StemFit®Basic02 medium may be aseptically aliquoted and stored at below -20 °C. Thawed StemFit®Basic02 medium may be stored at 2-8 °C for up to two weeks.
    Optional: We recommend storing the medium protected from light
  4. Before use, warm aliquots to room temperature and use immediately.
