Properties

Description

Acid-PEG25-NHS ester serves as a PEG linker incorporating both a carboxylic acid and an NHS ester moiety. Its hydrophilic PEG spacer improves solubility in water-based environments. The terminal carboxylic acid can react with primary amine groups when activated by agents such as EDC or HATU to form stable amide bonds. Additionally, this NHS ester allows for labeling primary amines t-present within proteins or other similar compounds containing amino functionalities.
