Is it possible to re‑freeze CD34⁺ progenitor cells after expansion in PromoCell Hematopoietic Progenitor Cell Expansion Medium XF?
After successful amplification, the expanded cells may be cryopreserved using an appropriate freezing medium (e.g. Cryo-SFM Plus, C-29920) and protocol, allowing their use in subsequent experiments at a later time.
