US Patent 12084720 Assessing graft suitability for transplantation

This invention relates to methods and compositions for assessing the suitability of a graft for transplantation or implantation by measuring total and/or specific cell-free nucleic acids (such as cf-DNA) and/or cell lysis. Specifically, the method comprising obtaining an amount of total cf DNA and/or graft-specific cfDNA released from a potential graft (e.g., ex vivo), e.g., prior to contacting of the potential graft with blood cells of a potential recipient, and/or subsequent to contacting of the potential graft or cells thereof with blood cells from a potential recipient, assessing the amount(s) to determine the suitability of the potential graft for transplantation or implantation.
