Medchemexpress LLC Boc-NH-PEG10-NHS ester | 3075546-11-8 | 98.0% | C32H58N2O16 | 100 MG

Boc-NH-PEG10-NHS ester is a PEG-based PROTAC linker used in the synthesis of PROTACs. PROTACs are molecules with two ligands connected by a linker; one targets an E3 ubiquitin ligase and the other targets a protein of interest. This mechanism exploits the intracellular ubiquitin-proteasome system for selective degradation of target proteins.

Medchemexpress LLC Hippuryl-His-Leu-OH hydrate (N-Benzoyl-Gly-His-Leu hydrate) | 207386-83-2 | 99.7% | 429.47 | 50 MG

Hippuryl-His-Leu-OH hydrate (N-Benzoyl-Gly-His-Leu hydrate) is a specific substrate for angiotensin-converting enzyme (ACE) I, used as a molecular tool for detecting ACE activity in in vitro experiments. It is hydrolyzed by ACE through competitive binding, producing hippuric acid, which can be quantified to assess ACE activity or screen for ACE inhibitors. The released His-Leu can also be detected via fluorescence.
