PEG

Fmoc-PEG4-NHS ester is a PEG linker containing an Fmoc-protected amine and an NHS ester. 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. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

S-Acetyl-PEG3-azide is a PEG linker containing an azide group and a sulfur acetyl group. The azide group enables Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG3-(CH2)3-NH2 TFA salt is a biotinylation reagent whicn can be coupled to carboxyl containing molecule or 5'phosphate groups to form stable amide bonds. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG5-alcohol enables Click Chemistry reactions with azide compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG5-acid has a propargyl group at one end and an acid group at the other end. The acid can react with primary amines to form a stable amide bond, activation will be needed. The PEG units enhances solubility of the molecule in aqueous environment. The propargyl group can be linked to azide-containing biomolecules via Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG4-alcohol is a biotinylation reagent containing a primary hydroxyl (OH) that cn be derivatized. The PEG spacer provides greater solubility to labeled molecules compared to reagents having only hydrocarbon spacers. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG5-t-butyl ester has one of the functional groups protected by t-butyl group. The protection can be removed under acidic conditions. The propargyl group forms triazole linkages with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The PEG units help improving the water-solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
