BPG-2700 Y-shape-PEG-Mal, MW 40k Inquiry

Synonyms: Y-shape-PEG-Maleimide

Y-shape-PEG-Mal is a high quality multi-arm PEG derivative with two linear methoxy polyethylene glycol and one linear polyethylene glycol modified linear polyethylene glycol at the end. Its terminal maleimide reacts with a mercaptan group at pH 5.0 to 6.5. Because of its large spatial structure, Y-type PEG is more selective than linear PEG. Polyethylene glycol arms have hydrophilicity and other excellent physical and chemical properties. For example, PEG chains can inhibit nonspecific binding of charged molecules to modified surfaces. Y-shaped PEG derivatives are chemically purified during synthesis and contain almost no activated bifunctional PEG by-products.
