PEG

m-PEG2-4-nitrophenyl carbonate is a PEG linker with a nitrophenyl carbonate moiety. NPC is reactive towards the amino group of lysine by means of stable urethane linkages. The hydrophilic PEG linker increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Sulfo DBCO-PEG4-Amine is a water-soluble carboxyl-reactive building block with extended PEG spacer arm. In the presence of of activators (e.g. EDC, or HATU), this reagent can be used to derivatize carboxyl groups or activated esters (e.g. The NHS ester) through a stable amide bond. The hydrophilic sulfonated spacer arm greatly improves water solubility of DBCO derivatized molecules and a provides a long and flexible connection. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Boc-N-bis(PEG3-azide) is a click chemistry PEG reagent with two terminal azide groups and a Boc protected amino group. The azide groups enable PEGylation via Click Chemistry. Boc can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

NH-bis(PEG3-azide) is a click chemistry PEG reagent containing an amino group with two azide groups. The amino group can react with carboxylic acids, activated NHS esters. The azide groups enable Click Chemistry with alkyne such as DBCO, BCN or propargyl reagents. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Mal-PEG2-amine TFA salt is a PEG linker containing a maleimide group and an amine group. The hydrophilic PEG spacer increases solubility in aqueous media. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. 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.

PEG3-(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.

Sulfo DBCO-Maleimide a water-soluble sulfhydryl reactive containing a maleimide group and a DBCO moiety. Maleimide group specifically and efficiently reacts with thiols to form stable thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
