Fmoc-N-amido-PEG36-acid (Fmoc-NH-PEG36-COOH) is a PEG derivative containing an Fmoc-protected amine and a terminal carboxylic acid. 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 terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond

Numerous applications have used Fmoc-N-amido-PEG36-acid. Some applications of Fmoc-N-amido-PEG36-acid include the development of flexible antibodies with non-protein hinges, the development of optimized liposomes for intracellular protein delivery, and the development of conjugates for SPECT imaging of cancer in vivo.
