噬菌体展示可以合成、选择和筛选大型多肽文库(100 × 1010个不同的成员)。从这样的库中选择可以识别出基本上任何期望目标的结合伙伴(Sarikaya等人,Annu Rev Mater Res 34:373 - 408,2004; Deutscher, Chem Rev 110:3196 - 3211,2010)。对小分子探针具有亲和力或反应性的多肽在许多应用中都很有吸引力,包括蛋白质的靶向、位点特异性标记。在这里,我们描述了选择和筛选方案,以鉴定短肽,可以选择性地结合和/或与小分子反应。
Phage display enables the synthesis, selection, and screening of large, polypeptide libraries (>1 × 1010different members). Selections from such libraries can identify binding partners to essentially any desired target (Sarikaya et al., Annu Rev Mater Res 34:373–408, 2004; Deutscher, Chem Rev 110:3196–3211, 2010). Peptides with affinity or reactivity to small molecule probes are attractive for numerous uses including the targeted, site-specific labeling of proteins. Here, we describe selection and screening protocols for the identification of short peptides that can selectively bind to and/or react with small molecules.
