该方案描述了使用表面等离子体共振技术的 PD-1/PD-L1 抑制剂的封闭测定。它采用双步固定策略和定制的缓冲系统来准确测量反应单位,有助于评估化合物或生物制剂的封闭率。此外,它还支持 PD-1/PD-L1 抑制剂的高通量鉴定。

我从事药物发现工作,寻找新的癌症免疫检查点抑制剂,如 PD-1、PD-L1。我的关键问题是,我们如何设计一个高通量的屏幕平台来加快这一速度?近年来,靶向PD-1、PD-L1的生物药物取得了重大进展。虽然小分子药物仍处于开发的早期阶段,但我们的目标是开发靶向 PD-1、PD-L1 的小分子药物。

均相时间分辨荧光、HTIF和af-ah-ly-zer是两种应用于PD-1、PD-L1抑制剂筛选的技术。小分子的溶解度和缓冲液不匹配是当前实验的主要挑战。
