多肽是一种优良的生物界面分子和诊断探针,具有渗透性好、周转时间短、成本低等优点。我们在这里报告了一种基于微阵列上原位单珠测序的高效多肽筛选策略。从10(5)文库中获得了两个与肿瘤生物标志物人表皮生长因子受体2(HER2)特异性结合的多肽YLFFVFER(H6)和KLRLEWNR(H10),其AKD值为10(-8)M。通过体内成像,H6和H10探针与纳米颗粒结合后,在异种移植小鼠的HER2阳性肿瘤组织中特异性聚集。
Peptides are excellent biointerface molecules and diagnostic probes with many advantages such as good penetration, short turnover time, and low cost. We report here an efficient peptide screening strategy based on in situ single bead sequencing on a microarray. Two novel peptides YLFFVFER (H6) and KLRLEWNR (H10) specifically binding to the tumor biomarker human epidermal growth factor receptor 2 (HER2) with aKD of 10(-8) M were obtained from a 10(5) library. Conjugated to nanoparticles, both the H6 and H10 probes showed specific accumulation in HER2-positive tumor tissues in xenografted mice by in vivo imaging.
