PEG

Azide-PEG-alcohol, MW 5,000 is a widely used PEGylation reagent that can "click" with an alkyne-containing molecule. Hdyroxyl group can be chemically altered depending on the end-goal of the polymer applications. Reagent grade, for research purpose.

Azide-PEG-alcohol, MW 10,000 is a "clickable" PEG polymer when reacted with alkyne-containing molecule. The click chemistry is a powerful and facile method in chemistry, biochemistry, medicine and pharmaceutical. Reagent grade, for research purpose.

Fmoc-N-amido-PEG-CH2COOH, MW 2,000 is a Fmoc-protected PEGylation reagent containing a carboxylic acid terminus. The carboxylic acid is readily available for reaction with a primary amine in the presence of HATU or EDC to form a stable amide bond. The Fmoc deprotection results in a terminal amine which can be used for many bioconjugation. Reagent grade, for research purpose.

N-Boc-N'-(PEG1-t-butyl ester)-L-Lysine-OH is the amino acid lysine with a Boc-protected α-amine and an amido-PEG1-t-butyl ester on its ε-amine. The carboxylic acid can be reacted with alcohols or amides, while the Boc and a t-butyl ester which can be later deprotected to perform further conjugation.

N-bis(Azide-PEG23)-N-(PEG24-Acid) is a branched PEGylation reagent containing an amino group with two azide groups. The amino group is reactive with carboxylic acids, activated NHS esters. 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.

N-(Amino-PEG23)-N-bis(PEG23-Azide) is a branched PEGylation reagent containing an amino group with two azide groups. The amino group is reactive with carboxylic acids, activated NHS esters. 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.

N-Boc-N'-(PEG1-t-butyl ester)-L-Lysine-NHS ester is the amino acid lysine with a Boc-protected α-amine, an amido-PEG1-t-butyl ester on its ε-amine, and an NHS ester on its C-terminus. The NHS can be easily displaced by amines to form an amide, while the Boc and t-butyl ester can be deprotected to perform further conjugation.

Methyltetrazine-amido-Tri-(acid-PEG1-ethoxymethyl)-methane is a click chemistry PEG reagent which contains three carboxylic acid groups and a methyltetrazine group. This reagent can react with TCO-containing compounds to form a stable covalent bond without the catalysis of Cu or elevated temperatures. The inverse-electron demand Diels-Alder cycloaddition reaction of TCO with tetrazines is the fastest bioorthogonal reaction with exceptional selectivity. 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-PEG-CH2COOH, MW 1,000 is an amine-protected PEGylation reagent. The terminal carboxylic acid, with addition of HATU or EDC, can react with primary amine to form a stable amide bond. The deprotection of amine can be done under basic condition for many bioconjugation. Reagent grade, for research purpose.
