Vitrification condition stabilizer for animal cell cryopreservation solution

摘要

(A) Amphoteric polymer compound carboxylated by reacting ε-poly-L-lysine with butyl succinic anhydride; (b) ε-poly-L-lysine reacted with butyl succinic anhydride and succinic anhydride. Or an amphoteric polymer compound selected from the group consisting of: an amphoteric polymer compound carboxylated by reacting ε-poly-L-lysine with a compound represented by formula I; Vitrification state stabilizer for animal cell cryopreservation solution comprising molecular compound and (d) epichlorohydrin cross-linked sucrose multimer polymer, and animal cell cryopreservation containing the vitrification state stabilizer The solution provides an animal cell cryopreservation solution having excellent vitrification ability.
