Fluorescent antibody probes showing antigen-dependent fluorescence responses were developed by N-terminal-selective reductive alkylation of IgGs.
通过IgGs的N端选择性还原烷基化制备出显示抗原依赖性荧光响应的荧光抗体探针。

Preparation of diverse glycans is essential to glycobiology, while syntheticallyusefulenzymes for this purpose are limited. This study discovered a general tolerance of galactosyltransferases (GalTs) toward uncommon donor UDP-galactosamine. A two-step strategy was devised to harness this property for the facile synthesis of GalNAc-glycosides.

In living color: Aurorakinase A (AKA) was imaged in livecells using a bioorthogonal two‐step reaction with a small molecule AKA inhibitor (see scheme) and a fluorescent reporter. The fluorescent molecule was localized to spindle poles and microtubules during metaphase, consistent with the localization of both endogenous and green fluorescent protein tagged AKA. By using this approach, changes in
活体颜色:使用小分子 AKA 抑制剂(见方案)和荧光报告基因的生物正交两步反应,在活细胞中对极光激酶 A (AKA) 进行成像。荧光分子在中期定位于纺锤体极和微管,与标记 AKA 的内源性和绿色荧光蛋白的定位一致。通过使用这种方法,还观察到了有丝分裂过程中 AKA 分布的变化。
