Fmoc-N-amido-PEG-CH2COOH, MW 3,400 is a heterobifunctional PEGylation reagent containing a carboxylic acid and Fmoc protected amine groups. The carboxylic acid reacts with a primary amine using activators, such as EDC or HATU, to form a stable amide bond. Fmoc can be deprotected under basic condition. Reagent grade, for research purpose.

Fmoc-N-amido-PEG-CH2COOH, MW 5,000 is a Fmoc protected amino PEG polymer. The carboxylic acid functional group can react with primary amines in the presecnce of activators, such as EDC or HATU, to form a stable amide bond. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further couplings. Reagent grade, for research purpose.

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.
