pGlu(7.5K)-PEG(2K)-Azide is a linear amphiphilic block copolymer comprised of polyethylene glycol (PEG) and polyamino acid having one COOH function per glutamic acid unit and a terminal azide group. The hydrophilic PEG increases solubility in aqueous media. pGlu is soluble in water(alkaline solution), dichloroacetic acid, chloroform, DMF, dioxane, and acetic acid. The terminal azide group can react with an alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Reagent grade, for research use only.
