Abstract

The present invention provides compositions (i.e., preservation solutions) for preserving biologies comprising at least one membrane penetrable sugar, at least one membrane impenetrable sugar, at least one anti-microbial agent, at least one anti-oxidant, adenosine, albumin, a salt, a buffer, and a chelating agent, and to methods of using such preservation solutions to preserve biologies.

Claims (14)

1. A non-cryogenic preservation solution for a biologic comprising:

about 0.1% w/v to about 12% w/v trehalose and about 2% w/v glucose;

about 0.01% w/v to about 25% w/v Dextran-70; and

mannitol; wherein the preservation solution does not contain a permeabilizer;

and wherein the non-cryogenic preservation solution functions without lyophilization, freeze-drying, vacuum drying and/or oven drying methods.

2. The preservation solution according to claim 1 further comprising an anti-microbial agent.

3. The preservation solution according to claim 1 wherein the anti-microbial agent is sulfanilamide.

4. The preservation solution according to claim 1 wherein trehalose is present at about 2% w/v, about 3% w/v, about 4% w/v, or about 5% w/v.

5. The preservation solution according to claim 1 wherein the solution comprises about 3% w/v trehalose and about 2% w/v glucose.

6. The preservation solution according to claim 1 wherein Dextran-70 is present at about 3% w/v.

7. The preservation solution according to claim 2 wherein the anti-microbial agent is present from about 0.001% to about 0.1%, from about 0.005% to about 0.075%, from about 0.01% to about 0.05%, or from about 0.015% to about 0.025%.

8. The preservation solution according to claim 7 wherein the anti-microbial agent is present at about 0.02%.

9. The preservation solution according to claim 1 wherein mannitol is present from about 0.11 mmol to about 1.1 mmol, or from about 0.44 mmol to about 0.77 mmol.

10. The preservation solution according to claim 1 wherein mannitol is present at 0.11 mmol, 0.44 mmol, 0.77 mmol, or 1.1 mmol.
