We developed a spongy-like porous polymer (spongy monolith) consisting of poly(ethylene-co-glycidyl methacrylate) with continuous macropores that allowed efficient in situ reaction between the epoxy groups and proteins of interest. Immobilization of protein A on the spongy monolith enabled high-yield collection of immunoglobulin G (IgG) from cell culture supernatant even at a high flow rate. In addition, immobilization of pepsin on the spongy monolith enabled efficient online digestion at a high flow rate.
我们开发了一种由聚（乙烯-co-甲基丙烯酸缩水甘油酯）组成的具有连续大孔的海绵状多孔聚合物（海绵状整体），允许环氧基团与感兴趣的蛋白质在原位进行有效反应。将蛋白 A 固定在海绵状整体上，即使在高流速下，也能从细胞培养上清液中高效收集免疫球蛋白 G（IgG）。此外，将胃蛋白酶固定在海绵状整体上，能够在高流速下进行有效的在线消化。
