Properties

Description

Acid-PEG13-NHS ester functions as a PEG linker featuring 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 amines when activated by agents such as EDC or HATU to form stable amide bonds. Additionally, the NHS ester allows for labeling of primary amines t-within proteins or other similar molecules containing amino functionalities.
