Claims (10)

1. A method of protecting, preserving and/or maintaining organs, tissues or cells ex vivo, comprising preserving the organs, tissues or cells with an effective amount of a composition comprising 6A-[(n-aminoalkyl)amino]-6A-deoxy-β-cyclodextrin.

2. The method of claim 1 , wherein the composition comprises the cyclodextrin closely combined with an antioxidant.

3. The method of claim 2 , wherein the antioxidant is resveratrol.

4. The method of claim 2 , wherein the antioxidant is curcumine.

5. The method of claim 2 , wherein the composition comprises an antioxidant/cyclodextrin molar ratio of between 1/1.5 and 1/150.

7. The method of claim 5 , wherein the antioxidant is curcumine.

8. The method of claim 1 , wherein the composition further comprises an impermeable agent and a buffer.

9. The method of claim 1 , wherein the organs are preserved in cold ischemia.

10. The method according to claim 1 , wherein the composition comprises 6A-[(3-aminopropyl)amino]-6A-deoxy-β-cyclodextrin, or 6A-[(2-aminoethyl)amino]-6A-deoxy-β-cyclodextrin, or a combination thereof.
