Abstract
Methods and devices for the removal of psoralens and psoralen photoproducts from blood products are described. The methods include contacting a psoralen- and irradiation-treated blood product with a resin capable of adsorbing psoralens and psoralen photoproducts. The removal process is particularly suitable for use with platelet concentrates and plasma because the process does not have a significant adverse effect on clotting factor function. The methods and devices can be incorporated with apheresis systems and other devices and procedures currently used to process blood products for transfusion.
