Y-shape-PEG-Alkyne

Y-shape-PEG-Alkyne is a high quality multi-arm PEG derivative with two alkynyl modified linear methoxy polyethylene glycol and one linear polyethylene glycol at the end. It can be used to react with molecules containing azides. Two alkynyl modified linear ethylene oxy polyethylene glycol and one linear polyethylene glycol at the ends selectively react with azides through a click chemical reaction. The reaction is simple, rapid, high selectivity and high yield. Because of its large spatial structure, Y-type PEG is more selective than linear PEG. Polyethylene glycol arms  have hydrophilic and other excellent physical and chemical properties. For example, PEG chains can inhibit nonspecific binding of charged molecules to modified surfaces.
