Description
Iodoacetamido-PEG3-NHS ester is a reactive PEG linker featuring an iodoacetamide group and an NHS ester, providing dual reactivity. The iodoacetamide acts as an efficient alkylating agent, forming covalent bonds with thiol groups, while the NHS ester enables rapid conjugation with primary amines under mild conditions.
Applications
Iodoacetamido-PEG3-NHS ester is used in site-specific protein labeling, bioconjugation, and drug delivery. It facilitates selective thiol modification of cysteine residues and efficient amine coupling, making it ideal for creating stable, targeted conjugates in biochemical and pharmaceutical research.
