A membrane suitable for immobilizing peptides and proteins is disclosed. The membrane is a flexible, polymeric, porous membrane which contains functional groups capable of covalently linking the peptides and proteins. The functional groups can be provided by reacting the membrane itself or a coating thereon with nucleophiles which provide -NH₂, -SH, -OH or -COOH functionality to the membrane surface. Additionally, surfaces containing -NH₂ groups can be further reacted with diisothiocyantes to provide an isothiocyanate functionality having enhanced covalent binding characteristics.
本发明公开了一种适用于固定肽和蛋白质的膜。这种膜是一种柔性高分子多孔膜,它含有能将肽和蛋白质共价连接的官能团。这些官能团可通过膜本身或其涂层与亲核物反应来提供,亲核物可为膜表面提供-NH₂、-SH、-OH 或-COOH 官能。此外,含有-NH₂基团的表面可进一步与二异硫氰酸盐反应,以提供具有增强共价结合特性的异硫氰酸盐官能团。
