Protein Modification Reagents

Chemical agents used to modify the amino acid side chains of proteins in order to alter their native charges, block or expose reactive binding sites, inactivate functional groups, and change functional groups to create targets for crosslinking and labeling.

Medchemexpress LLC Fluorescein-PEG4-acid | 1807518-76-8 | 96.3% | 654.68 | 50 MG

Fluorescein-PEG4-acid is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. 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.
