Supplier: ALADDIN SCIENTIFIC

Description: Aldeyde PEG is an amine reactive PEG derivative that can be used to modify biomolecules via available amine groups. The reaction between aldehyde group with ε-amine of lysine residues and the α-amine at the N-terminus produces an intermediate Schiff base. Further reduction with hydride will form a stable C-N bond. PEG aldehydes react with amine groups at a pH of from 5.5 to 9.5. Higher pH will result in multiple Pegylation with both terminal and lysine groups. Aldehyde PEG is a commonly used PEG reagent for n-terminus pegylation in proteins or peptides.

Description: Alkyne functionalized polyethylene glycol (Alk-PEG-X) is a bifunctional PEG derivative that can be used to modify proteins, peptides and other materials via Click Chemistry. Alkyne group can react with azide in aqueous solution catalyzed by copper. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.

Description: This full length Exendin 4 amide peptide is labeled with a fluorescent dye (FAM), Abs/Em = 494/519 nm, on its N-terminus. Exendin-4, an agonist of glucagon-like peptide 1 (GLP-1) receptor, induces release of insulin after food intake. Exendin-4 shares a 53% sequence homology with GLP-1. Derived from Gila monster, Heloderma suspectum, Exendin-4 has a longer half life than GLP-1 in the plasma, thus making it a more potent insulinotropic agent.
