Abstract
Official abstract text for this publication.
Methods and devices for sterilizing viscous peptide compositions which have shear thinning rheological properties at high concentrations.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for sterilizing a liquid peptide composition, wherein the peptide in the liquid peptide composition comprises IEIK13 as set forth in SEQ ID NO:3, and wherein the peptide is N-terminal acetylated and/or C-terminal amidated, the method comprising subjecting the liquid peptide composition to heat treatment performed at about 121° C. for about 25 minutes. 2. The method of claim 1 , wherein the method does not involve sterilizing filtration. 3. The method of claim 1 , wherein the liquid peptide composition has a peptide concentration within the range of about 0.01% and about 10%. 4. The method of claim 1 , wherein the method does not degrade the peptide. 5. A method for sterilizing a liquid peptide composition, wherein the peptide in the liquid peptide composition comprises IEIK13 as set forth on SEQ ID NO:3, and wherein the peptide is N-terminal acetylated and/or C-terminal amidated, the method comprising subjecting the liquid peptide composition to autoclave treatment. 6. The method of claim 5 , wherein the method does not involve sterilizing filtration. 7. The method of claim 5 , wherein the liquid peptide composition has a peptide concentration within the range of about 0.01% and about 10%. 8. The method of claim 5 , wherein the method does not degrade the peptide.
