基于DNA编码化合物库(DEL)的分子水平药物筛选分析相关试剂|百灵威-百灵威
    药物筛选是从不同来源化合物中寻找对机体有作用的物质并对其进行药效学评价,是开发新型药物的最重要的基础环节。药物筛选技术直接关系到先导化合物质量、研发效率以及成药可能性,随着新技术、新靶点的不断涌现,在传统药物筛选技术(已知活性化合物的筛选和高通量筛选)的基础上,一些新的药物筛选平台应运而生,如DNA编码化合物库(DEL)、蛋白降解靶向嵌合体(PROTAC)、基于片段的药物发现(FBDD)、基于结构的药物发现(SBDD)、计算机辅助药物设计和虚拟筛选(CADD)等。
    其中DNA编码化合物库(DEL)技术的原理是将待筛选的分子与一段独特的DNA序列在分子水平连接,进行DNA编码,类似于贴上独一无二的DNA“条形码”。将这些化合物与靶蛋白共同孵育,亲和力高的分子会和靶蛋白结合,洗去未结合的化合物,通过PCR扩增和DNA测序技术,读取与靶蛋白结合的化合物的DNA标签,确定编码对应的化合物分子,具有高通量、低成本、高灵敏度等优点。
    百灵威可提供基于DEL技术药筛分析相关产品,包括各类磁珠、 PCR扩增用试剂、缓冲液及相关耗材,种类齐全,质控严格,批次稳定性优异。
