生物大分子间的相互作用是一切生命现象的基础。近年来 ,噬菌体随机肽库已成为探索受体与配体之间相互作用结合位点、寻求高亲和力生物活性的配体分子、探测未知蛋白空间结构表位的有利工具 ,在蛋白分子相互识别的研究、新型疫苗的研制、以及药物的开发等领域具有广泛应用前景。本综述旨在介绍它在几个方面的重要应用 The interaction between biological macromolecules is the basis of all life phenomena. In recent years, the phage random peptide library has become a probe to explore the interaction between the receptor and ligand binding sites, seeking high affinity biological activity of ligand molecules to detect unknown protein spatial structure epitopes an advantageous tool in the mutual recognition of protein molecules Research, the development of new vaccines, and drug development has broad application prospects. This review is intended to introduce its important applications in several ways
