Properties

Description

Mal-amido-PEG24-NHS is a PEG linker containing a maleimide group and an NHS ester. The maleimide group allows for conjugation with thiol-containing biomolecules, forming a stable covalent bond. The NHS ester reacts with primary amines, such as those on proteins and amine-modified oligonucleotides, enabling further functionalization. The long hydrophilic PEG spacer (24 units) enhances solubility in aqueous environments, making this compound ideal for applications requiring enhanced water solubility and bioconjugation efficiency.
