    摘要: Branched monodispersed polyethylene glycol represented by formula (1). (X 1 is a functional group that reacts with a functional group present in a biofunctional molecule to form a covalent bond; n is an integer of 4-50 and represents the number of repeating units of ethylene oxide units; L 1 represents a single bond, -NH-, -L 2 -(CH 2 ) m1 -, or -L 2 -(CH 2 ) m1 -L 3 -(CH 2 ) m2 -; L 2 represents an ether bond, an amide bond, a urethane bond, or a single bond; L 3 represents an ether bond, an amide bond, or a urethane bond; and m1 and m2 each independently represent an integer of 1-5.)
