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.

Serum-free cryopreservation solution and preparation method and application thereof

A cryopreservation solution contains 0.01-50.0 g of bionic ice control materials, 5.0-30 mL of polyols, 1-30 g of water-soluble sugar, and 0-30 mL of serum, and a buffer in every 100 mL of the cryopreservation solution. It does not contain DMSO. When being used for the cryopreservation of mouse oocytes and embryos, the solution may achieve the same or an even higher cell and tissue survival rate and functional expression stability as or than a commercial cryopreservation solution (containing 15% DMSO), and has high preservation efficiency. The cryopreservation solution without DMSO or serum reduces parasitic biological contaminants in the commercial cryopreservation solution containing serum currently used in clinical practice.
