Azido-PEG11-azide is a aqueous soluble, monodisperse PEG linker containing two azide groups.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.

Propargyl-PEG5-beta-D-galactose is a Click Chemistry-ready crosslinker containing a propargyl group and beta-D-galactose. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield stable triazole linkages. D-galactose increases solubility in aqueous media and increases the selectivity of the PEGylation reaction. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG13-acid consists of an alkyne group and a carboxylic acid. The carboxylic acid reacts with amine groups to form amide bonds in the presence of EDC or HATU as an activator. The alkyne group is commonly used in copper catalyzed azide-alkyne Click Chemistry reactions. The hydrophilic PEG units enhance the solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Boc-PEG6-alcohol is a PEG linker containing a Boc protected amine group and a terminal hydroxyl group. The Boc protecting group can be removed under acidic conditions. The hydroxyl group can react to further derivatize the compound. The hydrophilic PEG linker increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-N-amido-PEG7-acid is a PEG linker containing an Fmoc-protected amine and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. 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.

Fmoc-N-amido-PEG9-acid is a PEG linker containing an Fmoc-protected amine and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. 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.

t-Boc-N-amido-PEG4-amine is a Boc proteced PEG linker containing an free amino group. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
