专利号:US-2024198316-A1 优先权日:2021-05-31 标题 :Synthetic polymeric porous medium with hierarchical multiple layer structure, its design, synthesis, modification, and liquid chromatographic applications 发明人:MAO HUIMING; XU FENG; YANG KE; HU XINMEI; HUANG XUEYING 权利人:SUZHOU SEPAX TECH INC 摘要:A synthetic polymeric porous medium with a core-shell(s) hierarchical layer structure and has an essentially homogeneous porous structure from inside to outside of the medium, whose core and shell(s) are covalently modified with distinct chemical functional groups or same functional group with different density. Here the methodologies for resin syntheses and core-shell(s) modifications and liquid chromatographic applications of the newly developed resins in the field of analysis and purification of Tween surfactants, virus-like particles (VLP)/vaccines/viral vectors/viruses, antibody, and mRNA are disclosed.
