General description

Y-shaped Acetaldehyde PEG. N-terminal amine reactive PEG in the presence of a reducing reagent; less reactive but more selective compared to linear PEG aldehydes; reacts at pH 5-8. JenKem Technology′s patented products, Y-shape PEG derivatives, also known as branched PEG derivatives, contain two linear methoxy PEG chains attached to a central active core. JenKem proprietary Y-shape PEGs are more selective, due to their sterically bulky structure.

Application

Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization
