Lipids & Polymers

Biotin-PEG-Mal, MW 7,500 is a PEG derivative with terminal biotin. Biotinylated polymer can strongly bind to proteins, such as avidin/streptavidin and is used for non-radioactive labeling as well as purification of proteins and other target molecules. The terminal maleimide is reactive with thiol containing molecule to generate a stable thioether bond. Reagent grade, for research purpose.

Thiol-PEG-OH, MW 1,000 is a hydroxylated PEG polymer which is reactive with maleimide to generate a covalent thiother bond. The terminal hydroxyl can further derivatize to other molecule. Reagent grade, for research purpose.

HO-PEG-NHS ester, MW 2,000 is a linear heterobifunctional polydisperse PEG with a succinimidyl ester. The polymer can couple with amino containing molecule to form an amide bond. Reagent grade, for research purpose.

HO-PEG-CH2CO2-NHS, MW 3,400 is an amine reactive PEGylation reagent. The coupling between amine and NHS ester forms a stable amide bond. The hdyroxyl moiety can further derivatize the compound. Reagent grade, for research purpose.

HO-PEG-NHS ester, MW 5,000 can react with protein/peptide or other amino molecule via formation of a stable amide bond. The hydroxyl group can further derivatize to other compound. Reagent grade, for research purpose.

m-PEG-Mes, MW 10,000 is a monofunctional PEG with a good leaving group methanesulfonyl. The polymer can be used for nucleophilic SN2 substitution reaction. Reagent grade, for research purpose.

m-PEG-Tos, MW 5,000 is a tosylate (sulfonate ester) polyPEG for nucleophilic substitution reaction (SN2). Reagent grade, for research purpose.

m-PEG-Tos, MW 10,000 is a monofunctional PEG with a good leaving group, toluenesulfonyl. The polymer can be used for nucleophilic SN2 substitution reaction. Reagent grade, for research purpose.

HO-PEG-Tos, MW 3,400 is a polyPEG which can be further derivatized by nucleophilic subsitution (SN2) reaction. Reagent grade, for research purpose.
