Mal-amido-PEG4-NHS - 95%, high purity , CAS No.756525-99-2
Basic Description Synonyms 3-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)-N-{15-[(2,5-dioxopyrrolidin-1-yl)oxy]-15-oxo-3,6,9,12-tetraoxapentadecan-1-yl}propanamide | D70130 | O-[N-(3-Maleimidopropionyl)aminoethyl]-O'-[3-(N-succinimidyloxy)-3-oxopropyl]triethylene glycol | Alpha-Maleimido Specifications & Purity ≥95% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description Mal-amido-PEG4-NHS is a PEG derivative containing a maleimide group and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.
