Cryoprotective agent quality
VM-1: proven vitrification protocol; widely used in cryobiology to minimize ice damage and support tissue viability; more affordable than M22.
M22: research-grade formulation; whole mammalian organs have been recovered from cryopreservation using M22-based protocols; best possible quality.
No cryoprotective agent - ice forms during freezing, with greater risk of cellular damage; lower quality preservation.
