应用
Polyethylene glycols (PEGs) are FDA approved hydrophilic polymers. They are non-toxic, non-immunogenic and non-antigenic, and are widely used in a variety of biomedical applications such as bioconjugation, drug delivery, surface functionalization, and tissue engineering. PEG-NHS is an amine reactive PEG that can react to amino groups of lysine(s) on proteins or other biologics; reaction occurs at room temperature in <1hr at pH 7-8. Stable linker between PEG and NHS ester.
