AMCA-PEG4-Acid is a fluroescent molecule with a Boc protecting group and a PEG linker with a terminal carboxylic acid moiety. AMCA-PEG4-Acid has an excitation at 345 nm and emission at 450 nm with a relatively large Stoke’s shift and resistance to photobleaching. The protected amine can be deprotected under mild acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media. 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. Reagent grade, for research purpose.
