An amine-reactive labelling reagent with hydrophilic PEG4 spacer arm.
|4 X 2mg||£154.80|
DBCO-PEG4-NHS Ester reacts specifically and efficiently with a primary amine (e.g., side chain of lysine residues or aminosilane-coated surfaces) at pH 7-9 to form a covalent bond. The hydrophilic polyethylene glycol (PEG) spacer arm imparts water solubility and provides a long and flexible connection that minimises steric hindrance involved with ligation to complementary azide-containing molecules.
