About Polyethylene Glycol (PEG) and PEGylation
General description of polyethylene glycol (PEG) and a complete listing of PEG-based biotinylation, crosslinker, and modification reagents.

Branched-chain PEG - Amine Reactive
Attach branched methyl-capped polyethylene oxide (PEO) moieties to amine groups. Increase solubility and stability and reduce immunogenicity of peptides and proteins.

Branched-chain PEG - Sulfhydryl Reactive
Attach branched methyl-capped polyethylene oxide (PEG) moieties to sulfhydryl groups. Increase solubility and stability and reduce immunogenicity of peptides and proteins.

Carboxy-PEG_n-Amine
Discrete-length polyethylene glycol compounds with carboxyl and amine ends.

Methyl PEO-NHS Ester PEGylation Reagents
Amine-reactive NHS ester based reagents allow you to attach methyl-capped polyethylene glycol (PEG) moieties to proteins to increase solubility, stability and reduce their immunogenicity.

Methyl-PEG_n-AmineDiscrete-length polyethylene glycol compounds with a terminal primary amine.

Methyl-PEO₁₂-Maleimide PEG Reagents
Sulfhydryl-reactive maleimide based PEGylation reagent allows you to attach methyl-capped polyethylene glycol (PEG) groups to increase solubility and stability and reduce their immunogenicity.
