General description

Y-shape Maleimide PEG. Thiol reactive PEG ; reacts at pH 5.0-6.5. 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

Applications of Y-Shape Peg Derivatives for Drug Delivery

The immune system protects the body from disease by resisting the invasion of foreign molecules into its cells, for example peptides and proteins are hydrolyzed by proteolytic enzymes; nucleic acids are hydrolyzed by nucleases; and most small molecules are eliminated in the liver and kidneys.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
