PEG

HO-PEG-CH2COOH, MW 3,400 is a PEG polymer with -COOH which is reactive with primary amines with activator, such as EDC or HATU, to form a stable amide bond. The hydroxyl group can be further derivatized. Reagent grade, for research purpose.

HO-PEG-CH2COOH, MW 5,000 is a heterobifunctional and water soluble PEG polymer with two terminal groups, i.e. hydroxyl and carboxylic acid. Both end groups are reactive and this PEG can be a good candidate for a crosslinking agent. Reagent grade, for research purpose.

m-PEG-Mal, MW 10,000 is a PEGylation reagent. Maleimide is reactive with thiol group between pH 6.5 to 7.5. The hydrophilic PEG chain enhances the water solubility properties of the compound. Reagent grade, for research purpose.

m-PEG-Mal, MW 20,000 is a polyPEG reagent with thiol reactive moiety. The maleimide can react with thiol containing molecule under physiological condition pH. Reagent grade, for research purpose.

m-PEG-Mal, MW 30,000 is a thiol reactive PEGylation reagent. PEG-MAL can be used for site specific protein (cysteine) and peptide modifications. Reagent grade, for research purpose.

m-PEG-Nitrophenyl Carbonate, MW 20,000 is an amine reactive polyPEG with a stable carbonate linker for PEGylation. Reagent grade, for research purpose.

Mal-PEG-Mal, MW 3,400 is a linear thiol reactive PEG polymer which is reactive with thiols. It can be used for PEGylation with cysteine amino acid or other thiol containing molecules. Reagent grade, for research purpose.

Mal-PEG-Mal, MW 5,000 is a PEG-based crosslinking agent that contains thiol reactive functional group. The maleimide groups can react with thiols between pH 6.5 to 7.5 to form a stable thioether bond. Reagent grade, for research purpose.

HO-PEG-Mal, MW 3,400 is a linear heterobifunctional polyPEG. The maleimide can react with thiol groups at pH 6.5 to 7.5 to form a thioether bond. The hydroxyl group can be further derivatized. Reagent grade, for research purpose.
