PEG

m-PEG-azide, MW 30,000 is a PEG polymer with an azide which can react with alkynes, DBCO and BCN through CuAAC/SPAAC Click Chemistry. Reagent grade, for research use only.

Azide-PEG-Azide, MW 1,000 is a homobifunctional click chemistry reagent for crosslinking through reaction with alkyne to form a stable triazole ring. Reagent grade, for research use only.

Azide-PEG-Azide, MW 3,400 is a homobifunctional click chemistry reagent for crosslinking through reaction with alkyne to form a stable triazole ring. Reagent grade, for research use only.

Azide-PEG-amine, MW 1,000 is a polyPEG containing azide and amine terminal groups. The azide can react with terminal alkynes for copper-catalyzed click chemistry or with DBCO/BCN for copper-free click chemistry. The amine group is reactive with activated NHS ester to form a stable amide bond. The hydrophilic polyPEG increases the compound's water solubility in aqueous media. Reagent grade, for research use only.

Biotin-PEG-Biotin, MW 2,000 is a homobifunctional PEG polymer. Biotin has strong binding with streptavidin and is widely used for molecule target detection. Reagent grade, for research use only.

Biotin-PEG-Biotin, MW 5,000 is a homobifunctional PEG polymer. Biotin has strong binding with streptavidin and is widely used for molecule target detection. Reagent grade, for research use only.

Biotin-PEG-Biotin, MW 10,000 is a homobifunctional PEG polymer. Biotin has strong binding with streptavidin and is widely used for molecule target detection. Reagent grade, for research use only.

Biotin-PEG-amine, MW 1,000 is a biotin PEG polymer containing a free amine group. The amine group is reactive with an activated NHS ester via formation of an amide bond. The hydrophilic PEG chain increases water solubility of the compound. Reagent grade, for research use only.

Biotin-PEG-Thiol, MW 10,000 is a biotin PEG polymer containing a thiol group. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The hydrophilic PEG chain increases water solubility of the compound.
