PEG

Amine-PEG-amine, MW 5,000 is a PEG polymer with two terminal amines. The amine is reactive with NHS ester to form a stable amide bond. The hydrophilic polyPEG increases the water solubility of the compound. Reagent grade, for research purpose.

Amine-PEG-CH2OOH, MW 2,000 is a PEGylation reagent containing one carboxylic acid group. The amine group is reactive with activated NHS esters. The carboxylic acid can react with primary amines in the presence of activator, such as EDC or HATU, to form a stable amide bond. The PEG polymer is aqueous soluble. Reagent grade, for research purpose.

Amine-PEG-CH2OOH, MW 3,400 is a heterobifunctional PEG polymercontaining amine and carboxylic acid moieties. The amine group is reactive with activated NHS esters. The carboxylic acid can react with primary amines to form a stable amide bond. Reagent grade, for research purpose.

Amine-PEG-CH2OOH, MW 5,000 is a popular bifunctional PEGylation reagent. The amine group is reactive with activated NHS esters. The carboxylic acid can react with primary amines in the presence of activator, such as EDC or HATU, to form a stable amide bond. This PEG polymer is highly water soluble and also soluble in most organice solvents. Reagent grade, for research purpose.

Amine-PEG-thiol, MW 2,000 is a PEG polymer with an amine group and thiol moieties on each end. The amine group is reactive with activated NHS ester to form a stable amide bond. The thiol group is reactive with maleimide or disulfides molecule. This PEG polymer is soluble in aqueous solution and most organice solvents. Reagent grade, for research purpose.

Amine-PEG-thiol, MW 5,000 is a heterobifunctional PEG polymer that consists of amine and thiol on each end. The amine group is reactive with NHS ester to form a stable amide linkage. The thiol group is reactive with maleimide or disulfides molecule. Reagent grade, for research purpose.

Amine-PEG-valeric Acid, MW 3,400 is a PEGylation reagent which contains a free amine and a terminal carboxylic acid. The amine group is reactive with activated NHS esters. PEG Acid can also be converted to a N-hydroxysuccinimide active ester which is widely used in bioconjugation. Reagent grade, for research purpose.

Amine-PEG-valeric Acid, MW 5,000 is a heterobifunctional PEG polymer that have an amine group and a carboxylic acid group. The amine group is reactive with activated NHS esters. Amino PEG acid can be used to modify proteins, peptides and other materials. Reagent grade, for research purpose.

Biotin-PEG-amine, MW 2,000 is a biotin PEG polymer containing a free amine group (-NH2). The amine group is reactive with an activated NHS ester via formation of an amide bond. The hydrophilic PEG chain increases water solubility of the compound. Reagent grade, for research purpose.
