Product Information

Description	Fmoc-N-amido-PEG1-acid is a PEG linker containing a Fmoc-protected amine and a terminal carboxylic acid. The Fmoc group can be deprotected under the basic conditions to obtain the free amine which can be used for further conjugations. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media.
