Peptide microarrays are becoming a promising alternative to protein microarrays due to the challenges associated with protein immobilization and purification. Here, we put forward a novel experimental-based approach that combines DNA-directed immobilization, nanografting, and atomic force height measurements to immobilize computationally designed cyclic peptide on an ultra-flat gold substrate. This procedure yields peptide-DNA nanoarrays, which can bind to the solvent-exposed site on the Beta-2-microglobulin (β2m).
由于蛋白质固定和纯化存在挑战，肽微阵列正成为蛋白质微阵列的一种有前景的替代方法。在此，我们提出一种基于实验的新方法，该方法结合了DNA定向固定、纳米接枝和原子力高度测量，以将通过计算设计的环肽固定在超平的金基底上。此过程产生肽-DNA纳米阵列，其可与β2-微球蛋白（β2m）上暴露于溶剂的位点结合。
