Bis-(Mal-PEG3)-PH-N-succinimidyl acetate
MCE 国际站：Bis-(Mal-PEG3)-PH-N-succinimidyl acetate
产品活性：Bis-(Mal-PEG3)-PH-N-succinimidyl acetate 是一种 PROTAC linker，属于 PEG 类。可用于合成 PROTAC 分子。
研究领域：PROTAC
作用靶点：PROTAC Linkers
In Vitro: PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.

文献和实验，一组使用 NaHS 处理，一组则不作处理；然后用荧光马来酰亚胺染料 Alexa Fluor 488 C5 maleimide（下文简称MAL，Invitrogen，A10254）标记半胱氨酸上的硫醇基团，使正常的半胱氨酸通过 -S- 与 MAL 连接，而硫巯基化的半胱氨酸通过二硫键 -S-S- 与 MAL 连接，如下图： 图 1. 文献 Fig. 6G，硫巯基化分析步骤 接下来加入 DTT，硫巯基化蛋白上特有的二硫键就会被解开，导致荧光 MAL 分子脱落，荧光信号减弱。所以，荧光信号发生变化就验证
