Basic Description Synonyms Mal-amido-PEG6-acid|1334177-79-5|Maleimide-NH-PEG6-CH2CH2COOH|1-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)-3-oxo-7,10,13,16,19,22-hexaoxa-4-azapentacosan-25-oic acid|3-[2-[2-[2-[2-[2-[2-[3-(2,5-dioxopyrrol-1-yl)propanoylamino]ethoxy]ethoxy]ethoxy]ethoxy]ethox Specifications & Purity 97% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description Mal-amido-PEG6-acid is a PEG derivative containing a maleimide group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. 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. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.
