Lipids & Polymers

DOPE-PEG-Azide, MW 5,000 is a polydisperse PEG covalently attached to a phospholipid. The polymer is an amphiphilic molecule with hydrophobic fatty acid chains and hydrophilic PEG head which enables lipid bilayer or micelles formation in water. The phospholipid PEG can be used to prepare liposome or nanoparticles for targeted drug delivery and is reactive with alkyne to form a triazole ring. Reagent grade, for research use only.

Biotin-PEG-Biotin, MW 2,000 is a homobifunctional PEG polymer. Biotin has strong binding with streptavidin and is widely used for molecule target detection. Reagent grade, for research use only.

Biotin-PEG-Biotin, MW 10,000 is a homobifunctional PEG polymer. Biotin has strong binding with streptavidin and is widely used for molecule target detection. Reagent grade, for research use only.

Biotin-PEG-amine, MW 1,000 is a biotin PEG polymer containing a free amine group. 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 use only.

Biotin-PEG-Thiol, MW 10,000 is a biotin PEG polymer containing a thiol group. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The hydrophilic PEG chain increases water solubility of the compound. Reagent grade, for research use only.

m-PEG-Biotin, MW 1,000 is a biotinylation reagent with strong binding affinity to streptavadin or avadin for molecular labeling/detection. Reagent grade, for research use only.

DSPE-PEG-COOH, MW 2,000 is a PEG polymer with hydrophilic phosphate head and hydrophobic lipid tails. The polymer can self-assemble to form lipid bilayers in water. The phospholipid polyPEG can be used as a drug nanocarrier for administration of nutrients and therapeutic drugs, such as liposome in mRNA or DNA vaccines. The terminal carboxylic acid can react with primary amine groups to form a stable amide bond. The long PEG spacer increases reagent's solubility in aqueous media. Reagent grade, for research use only.
