PEG

Fmoc-PEG12-alcohol is a PEG linker containing an Fmoc-protected amine and a terminal hydroxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-PEG24-alcohol is a PEG linker containing an Fmoc-protected amine and a terminal hydroxyl group. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

TCO-PEG12-amine is a PEG linker featuring a trans-cyclooctene and a primary amine. The amine is a versatile group which can react with carboxylic acids, NHS esters, or carbonyls while the TCO function is applied towards click chemistry with tetrazine-containing compounds.

m-PEG-Propargyl, MW 2,000 is an alkyne functionalized PEG derivative. The alkyne is reactive with azide molecule in the presence of copper catalyst to form a triazole linkage. Reagent grade, for research purpose.

m-PEG-Propargyl, MW 5,000 is a monofunctional PEG derivative with terminal alkyne for click chemistry with azide in the presence of copper catalyst. Reagent grade, for research purpose.

Azide-PEG8-Tos is a small PEG linker featuring an azide and a tosylate. Tosylates are good leaving groups which are easily displaced by nucleophiles while azide is a click chemistry motif which is used to react with terminal alkynes or strained cyclooctynes.

4-[methyl(phenyl)amino]butanoic acid

PCL(1k)-mPEG(1k) is a block copolymer with polycaprolactone (PCL) as a hydrophobic segment and PEG as a hydrophilic block. The polymer is amphipathic and can self-assemble in aqueous media to form micelle which can be used to prepare nanoparticles for drug encapsulation in nanomedicine/drug delivery. The polyester PCL is biodegradable via hydrolytic attack on the ester bonds. Reagent grade, for research purpose.
