PEG

Amino-PEG24-acid is a very popluar PEG linker with great water solubility.The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG12-azide is a aqueous soluble monodisperse PEG linker. The azide group can react with alkyne, BCN, DBCO via Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG24-azide is a monodisperse, aqueous soluble PEG linker. The azide group is reactive with alkyne, BCN, DBCO via Click Chemistry to form a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG36-azide is a long chain, monodisperse PEG reagent containing an azide group. It is soluble in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Thiol-PEG8-acid is a PEG linker containing a thiol group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.
