Abstract: A grafted nonwoven substrate is disclosed having average fiber sizes of 0.7 to 15 microns, and a void volume of 50 to 95%, and a polymer comprising anionic monomer units grafted to the surface of the nonwoven substrate. The article may be used as a filter element to purify or separate target materials, such as monoclonal antibodies (MAb), from a fluid mixture.

Abstract: A grafted nonwoven substrate is disclosed having average fiber sizes of 0.7 to 15 microns, and a void volume of 50 to 95%, and a polymer comprising cationic aminoalkyl(meth)acryloyl monomer units grafted to the surface of the nonwoven substrate. The article may be used as a filter element to purify or separate target materials, such as oligonucleotides or monoclonal antibodies (MAb), from a fluid mixture.
Abstract translation: 公开了接枝非织造基材,其平均纤维尺寸为0.7-15微米,空隙体积为50至95%,以及包含接枝到非织造基材表面的阳离子氨基烷基(甲基)丙烯酰基单体单元的聚合物。 该制品可以用作过滤元件以从流体混合物纯化或分离靶物质,例如寡核苷酸或单克隆抗体(MAb)。
