    • Disclosed is a continuous process for separating or extracting proteins from a low grade mixture of a protein of interest, other proteins, impurities, and salts in a continuous simulated moving bed separation process. The invention provides for direct extraction of heme protein and plant protein from a crude mixture of such proteins, other proteins, impurities and salts using the chromatographic technique of simulated moving bed (SMB) continuous chromatography. The SMB process combines the steps of feed loading, adsorbent washing, product elution, adsorbent regeneration, and adsorbent equilibration. The novel strong anion exchange resin adsorbent is a quaternary amine cross-linked microcellulose wherein the microcellulose is cross-linked with epichlorohydrin and the quaternary amine is 2,3-epoxypropyltrimethyl-ammonium chloride which exhibits selective adsorption of proteins and complete regeneration. Purified protein separated in this manner may provide human health benefits by providing greater medicinal and nutrition opportunities from low quality protein sources.
    • 公开了在连续模拟移动床分离过程中从目的蛋白质,其它蛋白质,杂质和盐的低级混合物中分离或提取蛋白质的连续方法。 本发明提供使用模拟移动床(SMB)连续层析的色谱技术从这种蛋白质,其他蛋白质,杂质和盐的粗混合物中直接提取血红素蛋白和植物蛋白。 SMB方法结合了进料负载,吸附剂洗涤,产物洗脱,吸附剂再生和吸附剂平衡的步骤。 新型强阴离子交换树脂吸附剂是季铵交联微纤维素,其中微纤维素与表氯醇交联,季胺是显示出蛋白质选择性吸附和完全再生的2,3-环氧丙基三甲基氯化铵。 以这种方式分离的纯化蛋白质可以通过从低质量蛋白质来源提供更大的药物和营养机会来提供人体健康益处。
