PEG

Azido-PEG1-NHS ester is a click chemistry PEG reagent with broad application. Azide(N3) group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research purpose.

Mal-PEG1-acid is a PEG linker containing a maleimide group with a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. 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.

Mal-PEG8-acid is a PEG linker containing a maleimide group with a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. 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.

Azido-PEG1-PFP ester is a click chemistry PEG linker containing azide and PFP ester moities. The azide can participate in copper-catalyzed Click Chemistry reactions with alkynes, DBCO and BCN to form triazole groups. The PFP ester is amine-reactive and is less susceptible toward hydrolysis compared to NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG3-PFP ester is a PEG reagent consistig of an azide and PFP ester moities. The azide is reactive with copper-catalyzed Click Chemistry reactions with propargyl, copper-free click chemistry with DBCO and BCN. The PFP ester is amine-reactive and is less susceptible toward hydrolysis compared to NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG5-PFP ester is a linker compound containing azide and PFP ester moities. The azide can participate in Click Chemistry reactions with alkynes, DBCO and BCN to form triazole groups. The PFP ester is amine-reactive and is less susceptible toward hydrolysis compared to NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG6-PFP ester is a a high purity PEG linker containing azide and PFP ester moities. The azide can participate in Click Chemistry reactions with alkynes, such as DBCO and BCN to form triazole groups. The PFP ester is amine-reactive and is less susceptible toward hydrolysis compared to NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG8-PFP ester is a monodisperse PEG linker consisting of an azide and PFP ester moities. The azide can participate in Click Chemistry reactions with alkynes, DBCO and BCN to form triazole groups. The PFP ester is amine-reactive and is less susceptible toward hydrolysis compared to NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-PEG17-acid is a PEG linker containing two terminal carboxylic acid groups. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acids 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.
