Zusammenfassung: | To provide methods for producing pathogen-reduced platelet compositions that can be conveniently implemented, that effectively reduce the level of pathogens, and that provide a treated material that retains beneficial biological activity.SOLUTION: 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 electron beam radiation. The methods realize the irradiation with the electron beam radiation at doses effective to reduce the pathogen content of the compositions while retaining highly beneficial bioactivity of the compositions. Also disclosed are compositions preparable by the methods, and methods and compositions involving the use of electron beam-treated materials.SELECTED DRAWING: Figure 1
【課題】実行しやすく、病原体のレベルを効果的に減らし、有益な生物学的活性を保持する処理された材料を提供するようにした、病原体減少血小板組成物を作る方法を提供する。【解決手段】電子ビーム放射線で血小板組成物(例えば、血小板濃縮物および/または血小板溶解物)を処理するための方法が開示される。ここで、組成物は、電子ビーム放射線の照射中に凍結状態にある。この方法は、組成物の非常に有益な生物活性を保持しながら、該組成物の病原体含有量を減少させるのに有効な線量で電子ビーム放射線を照射することができる。この方法により調製可能な組成物、ならびに電子ビーム処理された材料の使用を含む方法および組成物も開示される。【選択図】図1 |
