Fmoc-PEG8-NHS ester Chemical Properties,Uses,Production
Description
Fmoc-PEG8-NHS ester is a PEG linker containing an Fmoc-protected amine and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
Uses
Fmoc-NH-PEG8-NHS ester is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
reaction suitability
reaction type: Pegylations
reagent type: cross-linking reagent
IC 50
PEGs; Alkyl/ether
