ABSTRACT:
Compositions and methods for the reversible preservation of biological samples are provided. The compositions include natural polymers such as pullulan or acacia gum, including derivations and modifications thereof, which are usefull as a reversible preservation solution. A method is provided for using pullulan or Acacia Gum to isolate and reversibly preserve a biological specimen in a dormant state at room temperature for an extended period with minimal damage to the specimen. The compositions and methods disclosed may also be used to create reversibly preserved biological specimens and biological receptors for use in biosensors.
