PEG

m-PEG-thiol, MW 10,000 is a thiol PEG polymer which is reactive with maleimide, SPDP, alkene, and disulfides. Thiol group can also interact with transition metal forming a metal-thiolate complex. Reagent grade, for research purpose.

m-PEG-thiol, MW 20,000 is a maleimide reactive PEG polymer via formation of a stable thioether bond. Reagent grade, for research purpose.

DBCO-NHCO-PEG4-NHS ester is a PEG linker containing NHS ester that is able to react specifically and efficiently with primary amines such as 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 can also provide a long and flexible connection that minimizes steric hindrance during ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG5-succinimidyl carbonate is a PEG linker with an attached succinumidyl carbonate group. The succinimidyl carbonate group is a good leaving group and commonly reacts with amine nucleophiles. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Mal-N-bis(PEG2-t-butyl ester) is a branched maleimide ester. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. The t-butyl pester can be hydrolyzed under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG4-succinimidyl carbonate is a PEG linker containing a succinumidyl carbonate group. The succinimidyl carbonate group is a good leaving group and commonly reacts with amine nucleophiles. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
