DBCO-PEG4-NHS Ester is a click chemistry PEG reagent containing NHS ester that is able to react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mal-amido-PEG4-alkyne is a short PEG linker featuring a maleimide and a terminal alkyne. Maleimide is a covalent ligand used for linking thiols such as those in cysteines residues in proteins, while terminal alkynes can be used in copper (I) click chemistry with azides on target molecules.
