PEG

TCO-PEG3-amine is a click chemistry crosslinking reagent. It can be used to derivatize NHS activated esters through a stable amide bond or carboxyl groups in the presence of of activators (e.g. EDC, or HATU). TCO enable click chemistry with tetrazine. PEG spacer improves water solubility. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azide-PEG-amine, MW 2,000 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 purpose.

m-PEG-ONH2 MW 2,000 is an aminooxy PEG polymer which can react with an aldehyde or ketone molecule to form a stable oxime linkage. The hydrophilic PEG chain increases water solubility of the compound in aqueous media. Reagent grade, for research purpose.

(1,3-dioxoisoindolin-2-yl)-O-PEG-OH, MW 2,000 is a bifunctional PEG polymer which one site can undergo removal to form an aminooxy. The reactive hydroxyl group can be modified into different functional group of interest. Reagent grade, for research purpose.

m-PEG-Azide, MW 2,000 is a click chemistry PEG polymer. Azide undergoes click chemistry with alkyne-containing molecule, such as DBCO/BCN and terminal alkyne. When the PEG-azide is clicked to other molecule, water solubility of the new compound is enhanced significantly. Reagent grade, for research purpose.

Mal-PEG8-t-butyl ester is a PEG linker containing a maleimide group and a t-butyl ester group. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

PEG6-(CH2CO2H)2 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. Please contact us for GMP-grade inquiries.

Azide-PEG-alcohol, MW 2,000 is a PEG polymer with an azide and hydroxyl group. The azide can react with alkyne for both Copper-Catalyzed Azide-Alkyne Cycloaddtion (CuAAC) and Strain-Promoted Azide-Alkyne Cycloaddtion (SPAAC) . The OH group can easily undergo further derivatization. Reagent grade, for research purpose.

(1,3-dioxoisoindolin-2-yl)-O-PEG-OMe, MW 2,000 is a methoxy polyethylene glycol with an end group which can be removed to form an aminooxy. Reagent grade, for research purpose.
