Abstract
A serum-free cryopreservation solution contains a biomimetic ice control material, a polyol, a water-soluble sugar, and a buffer solution margin. The bionic ice control material can be polyvinyl alcohol or an amino acid compound. The cryopreservation liquid of the present invention uses the bionic ice control material as the main component, does not contain serum, has low toxicity, and can achieve a cell survival rate that is the same as, or higher than, existing cryopreservation solutions.
