Fmoc-PEG4-NHS ester Chemical Properties, Uses, Production

Description

Fmoc-PEG4-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

Alpha-(fmoc-amino)-omega-(succinimidyl propionate) tetra(ethylene glycol)

reaction suitability

reaction type: Pegylations
reagent type: cross-linking reagent

IC 50

PEGs; Alkyl/ether
