PEG

Azide-PEG-Azide, MW 10,000 is a PEGylation reagent that has two terminal azide moieties. The azide can react with alkynes containing molecule such as DBCO/BCN via copper free click chemistry or with any other terminal alkyne via copper-catalyzed click chemistry. Reagent grade, for research purpose.

NHS-PEG4-(m-PEG12)3-ester is a monodisper branched PEG linker with a terminal NHS ester. It 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.

N-Benzyl-N-bis(PEG3-t-butyl ester) is a PEG linker that contains a benzyl group and two PEG3-t-butyl ester groups. The benzyl group acts as a protecting group for the amine and can be deprotected via hydrogenolysis. The t-butyl ester groups can be removed under acidic conditions. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Benzyl-N-bis(PEG3-acid) is a PEG linker that contains a benzyl group and two PEG3-acid groups. The benzyl group acts as a protecting group for the amine and can be deprotected via hydrogenolysis. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. PEG3 linker increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG7-NHS ester contains a propargyl group and an NHS ester. As an amine reactive reagent, this product can be used for derivatizing peptides, antibodies, amine coated surfaces etc. In the presence of copper catalyst, propargyl group reacts with azide to yield a stable triazole linkage. The PEG units help increase the hydrophilicity of the reagent. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-N-Amido-PEG5-propargyl comprises a propargyl group and Boc-protected amine. The propargyl group reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-N-Amido-PEG6-propargyl can be used in copper catalyzed Click Chemistry reactions with azides. The Boc group can be removed under mild acidic conditions to yield the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-Aminooxy-PEG3-oxyamine is a PEG crosslinker with a t-Boc protected aminooxy and a free aminooxy group. The terminal oxyamine group can react with an aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage. t-Boc can be removed under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

Aminooxy-PEG3-NH-Boc is a PEG linker containing an aminooxy group and a Boc protected amine group. The hydrophilic PEG spacer increases solubility in aqueous media. The aminooxy group can be used in bioconjugation. It reacts with an aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage. The protected amine can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.
