Abstract
Disclosed are methods for treating platelet compositions (e.g. platelet concentrates and/or platelet lysates) with electron beam radiation, where the compositions are in a frozen state during irradiation with the e-beam radiation. The methods can be conducted using e-beam radiation at doses effective to reduce the pathogen content of the compositions while retaining highly beneficial bioactivities of the compositions. Also disclosed are compositions preparable by the methods, and methods and compositions involving the use of the e-beam treated materials.
Claims10
A method for making a pathogen reduced platelet composition, comprising:
- irradiating a frozen composition comprising a platelet lysate with electron beam radiation having an energy level of 5 MeV to 15 MeV,
- wherein the irradiating is conducted to apply 60 kGy to 100 kGy of electron beam radiation to the frozen composition,
- wherein the electron beam radiation is applied to a first side of the frozen composition and to a second side of the frozen composition opposite the first side, and wherein a thickness of the frozen composition between the first side and the second side is 0.5-5 cm.
