Method for removing a pathogen-inactivating compound such as psoralen from a biological fluid such as blood or a blood product. One such method involves treating a blood product which contains a nucleic acid-containing pathogen to be inactivated. This method includes adding a pathogen-inactivating compound such as psoralen to the blood product; irradiating the psoralen and the blood product to form a mixture comprising the blood product, free psoralen, and low molecular weight psoralen photoproducts; and contacting the mixture with a hypercrosslinked resin to remove at least substantially all of the free psoralen and the low molecular weight psoralen photoproducts. A hypercrosslinked resin in this method preferably eliminates a wetting step that a number of other types of resins require before being used to adsorb the pathogen inactivating compound.
从
生物液体(如血液或血液制品)中去除一种病原体灭活化合物(如紫荆素)的方法。其中一种方法涉及处理含有
核酸病原体的血液制品以进行灭活。该方法包括向血液制品中添加病原体灭活化合物(如紫荆素);照射紫荆素和血液制品以形成含有血液制品、游离紫荆素和低分子量紫荆素光产物的混合物;并将该混合物与超交联
树脂接触,以去除至少几乎所有的游离紫荆素和低分子量紫荆素光产物。在该方法中,超交联
树脂优选地消除了其他类型的
树脂在用于吸附病原体灭活化合物之前需要进行的浸润步骤。
