描述了一种以氧化糖原为封端剂将蛋白质包埋在酰肼活化载体中的方法。这种方法是以人血清白蛋白(HSA)为模型结合剂进行的。通过对该方法的优化,得到了蛋白质含量为43(±1)mg HSA/g载体的多孔二氧化硅。包埋的人血清白蛋白载体可以保留低质量药物(S-华法林),并且具有与可溶性人血清白蛋白相当的活性和平衡常数。研究还发现,这种方法也可以用于质量在5.8 kDa到150 kDa之间的其他蛋白质和结合剂。
A method is described for the entrapment of proteins in hydrazide-activated supports using oxidized glycogen as a capping agent. This approach is demonstrated using human serum albumin (HSA) as a model binding agent. After optimization of this method, a protein content of 43 (± 1) mg HSA/g support was obtained for porous silica. The entrapped HSA supports could retain a low mass drug (S-warfarin) and had activities and equilibrium constants comparable to those for soluble HSA. It was also found that this approach could be used with other proteins and binding agents that had masses between 5.8 and 150 kDa.
