Vasodilators

Methoxy PEG NHS Ester (SCM PEG). Amine reactive PEG towards the amino groups of lysine(s) on proteins or other biologics reaction occurs at room temperature in &lt1hr at pH 7-8.

Application Polyethylene glycols (PEGs) are FDA approved hydrophilic polymers. They are non-toxic, non-immunogenic and non-antigenic, and are widely used in a varity of biomedical applications such as bioconjugation, drug delivery, surface

Methoxy PEG Maleimide. Selective for thiol groups on cystein side chains reacts at pH 5.

Methoxy PEG Hydrazide reacts with aldehydes and ketones to give stable hydrazones in a single step it can also react with activated carboxylic acids. Application Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker,

Application Activated PEG derivatives can be used to modify peptides, proteins, or in other bioconjugation applications. PEGylated materials have found broad use in drug delivery systems, virology, and immunology, as the incorporation of PEG

Application Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization Legal Information Product of JenKem Technology
