Amino-PEG4-CH2COOH With CAS.195071-49-9 Is For Chmical Modifications.

Introduction

Amino-PEG4-CH2COOH With CAS.195071-49-9 is a monodentate coboxyl-terminated polyethylene glycol (PEG)-containing reagents with either a methyl ether, hydroxyl, azido, or triplebonds. It has defined molecular weights and spacer lengths and are used for modifying Proteins or surfaces witch containing amine groups such quantum dots, self-assembled monolayers and magnetic particles. Functionalization of solid surfaces with polyethylene glycol spacers significantly reduces nonspecific protein binding.
