General description

8arm PEG Maleimide. Crosslinks into hydrogels. MAL is selective for thiol groups on cystein side chains; reacts at pH 5.0-6.5. 8ARM(TP)-PEG with tripentaerythritol core has a lower polydispersity and higher molecular weight accuracy compared with the generic 8ARM-PEG with a hexaglycerin core.

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.
