Description

m-PEG24-NHS ester features a 24-atom methoxy-terminated polyethylene glycol chain linked to an NHS ester functional group, enabling efficient conjugation to primary amines under physiological conditions. This hydrophilic linker enhances solubility and reduces non-specific binding in biological applications.

Application

m-PEG24-NHS ester serves as a versatile, water-soluble linker for conjugating biomolecules via amine-reactive coupling. Its long polyethylene glycol (PEG) chain provides enhanced solubility and reduced non-specific binding, while the NHS ester functionality enables efficient reaction with primary amines under physiological conditions. Ideal for bioconjugation workflows, it offers excellent stability in aqueous media and simplifies purification through its hydrophilic character.
