    • A process for the removal of endotoxins from a biological product, particularly a blood plasma fraction such as albumin, comprises contacting the biological product with a cross-linked hydrophilic matrix comprising a copolymer of allyl dextran and N,N'-methylene bisacrylamide under conditions effective to bind endotoxins in the biological product to the matrix, and recovering purified biological product from which endotoxins have been removed. After recovery of the purified biological product, the matrix can be regenerated under conditions effective to elute bound endotoxins from the matrix.
    • 用于从生物产物,特别是血浆级分如白蛋白中去除内毒素的方法包括使生物产物与包含烯丙基葡聚糖和N,N'-亚甲基双丙烯酰胺的共聚物的交联的亲水基质在有效的条件下接触 将生物制品中的内毒素与基质结合,并回收已除去内毒素的纯化生物制品。 在纯化的生物产物回收之后,可以在有效地从基质中洗脱结合的内毒素的条件下再生基质。
