Y-shape-PEG-COOH is a high quality multi-arm PEG derivative. It terminates in a carboxylic modification of two linear methoxy polyethylene glycol and one linear polyethylene glycol for amino-selective reactions with peptide-conjugating agents such as NHS, DDC and EDC. The total molecular weight of a Y-shaped PEG is the sum of the molecular weights of all three arms. 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.
