A chemically active membrane having a large surface area is provided in which a hydrophilic, microporous, skinless, polyamide membrane (12) is chemically bound to a residue of an activating agent which is capable of reacting with a biologically active material. The chemically active membrane, formed by reacting a hydrophilic, microporous, skinless, polyamide membrane (12) with an activating agent may be used to prepare a biologically active membrane (10) having a large surface area which comprises an acceptor molecule such as an monoclonal antibody, a polyclonal antibody, an antigenic substance, a glycoprotein, Protein A, a lectin, a carbohydrate, an anzyme substrate, a cofactor, an inhibitor, a hormone, an IgG class of immunoglobulin, carrier protein, a receptor, heparin, a coagulation factor, or a histone covalently bound to the hydrophilic, microporous, skinless, polyamide membrane (12) by reacting the chemically activate membrane with the acceptor molecule.
本发明提供了一种具有大表面积的化学活性膜,其中亲水、微孔、无皮聚酰胺膜(12)与活化剂残留物化学结合,活化剂残留物能够与生物活性材料发生反应。通过亲水、微孔、无皮、聚酰胺膜(12)与活化剂反应形成的化学活性膜可用于制备具有大表面积的生物活性膜(10),该生物活性膜包含受体分子,如单克隆抗体、多克隆抗体、抗原物质、糖蛋白、蛋白质 A、凝集素、蛋白质 B、蛋白质 C、蛋白质 D 和蛋白质 E、蛋白 A、凝集素、碳水化合物、酶底物、辅助因子、抑制剂、激素、IgG 类免疫球蛋白、载体蛋白、受体、肝素、凝血因子或组蛋白,通过化学活化膜与受体分子反应,共价结合到亲水性微孔无皮聚酰胺膜(12)上。
