Description and Uses

m-PEG8-acid is a PEG linker containing a terminal carboxylic acid. 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.

m-Peg8 Acid is used in the detection of antibiotic residues by nanogold probe surface plasmon resonance.
