Mal-PEG8-COOH Chemical Properties, Uses, Production

Description

Mal-amido-PEG8-acid is a PEG linker containing a maleimide group and a terminal carboxylic acid. 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. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.

Uses

31-(2,5-Dihydro-2,5-dioxo-1H-pyrrol-1-yl)-29-oxo-4,7,10,13,16,19,22,25-octaoxa-28-azahentriacontanoic Acid is reactant in the light-induced endosomal lysis events in fibroblast, normal, and carcinoma cell lines using a colloidal mesoporous silica (CMS) nanoparticle.
