Until is a biotechnology company developing reversible cryopreservation systems for human organs. Its work centres on vitrification - a process that cools biological tissue to subzero temperatures without forming ice crystals - and the engineering required to re-warm organs uniformly for transplantation. The company describes its goal as building a “pause button” for biology, with the aim of extending the viability of donor organs beyond the narrow time window imposed by current cold-storage methods.
The company’s technical domains span cryobiology, organ preservation, vitrification and cryopreservation systems engineering. Its primary product is an engineered workflow designed to safely preserve and then rewarm donor organs for transplant. Until operates within the organ transplantation, medical and biotechnology sectors.
