  • Publication number: 20240081322
    Abstract: An organ preservation and/or perfusion solution for an isolated tissue or organ is provided. The solution comprises dextran, glucose, calcium ions, a buffer, and water, has a pH of 6.6 to 7.8, and is sterile based on having been subjected to heat sterilization. A method of preparing the solution also is provided. The method comprises combining dextran, glucose, calcium ions, buffer, and water to obtain an initial solution, adjusting the pH of the initial solution to 7.0 to 7.8 if needed, and subjecting the initial solution to heat sterilization, thereby obtaining the organ preservation and/or perfusion solution. A method of preserving and/or perfusing an isolated tissue or organ also is provided. A method for flushing, storage, and/or transportation of an isolated lung after removal from a donor in preparation for eventual transplantation into a recipient also is provided.

  • Publication number: 20230284612
    Abstract: Serum albumin is an important molecule in human and animal blood. It provides oncotic pressure and acts as a transportation agent, delivering nutrients from the blood to the tissue and removing waste products from the tissue to the blood. This invention describes an organ preservation and/or perfusion solution which comprises acetylated serum albumin, as well as method of making and using such a solution, and uses of acetylated serum albumin itself. The acetylated serum albumin utilised in the present invention can protect the vascular endothelium during perfusion of an isolated organ or tissue.
