噬菌体肽库是将一段编码外源短肽的寡聚核苷酸整合到噬菌体基因中 ,以融合蛋白的形式在噬菌体表面表达 ,从而构建成序列不同的特定长度的小肽集合。一般采用生物亲合选择系统淘选噬菌体肽库。随着此项技术的不断完善和发展 ,噬菌体肽库已在许多领域得到了广泛的运用 The phage peptide library integrates an oligonucleotide encoding the exogenous short peptide into the bacteriophage gene to express on the surface of the bacteriophage in the form of a fusion protein so as to construct a small peptide collection of different specific lengths. Generally use biological affinity selection system panning phage peptide library. With the continuous improvement and development of this technology, the phage peptide library has been widely used in many fields
