Properties

Description

Acid-PEG9-NHS ester is a PEG linker that features both a carboxylic acid and an NHS ester. The hydrophilic PEG spacer enhances solubility in aqueous solutions. The terminal carboxylic acid can react with primary amine groups when activated by agents such as EDC or HATU, resulting in stable amide bond formation. This NHS ester is suitable for labeling primary amines t-found in proteins, amine-modified oligonucleotides, and other molecules containing amino groups.
