PEG

Azidoethyl-SS-ethylalcohol is a Click Chemistry-ready crosslinker. The azide group enables Click Chemistry. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG5-t-buyl ester is a PEG linker containing a t-butyl ester. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-PEG5-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.

Propargyl-PEG8-t-butyl ester is a PEG reagent with an alkyne group and a t-butyl group. The alkyne group enables the formation of triazole linkage with azide-bearing compounds or biomolecules; copper is required as a catalyst. The t-butyl group can be hydrolyzed under acidic conditions. The hydrophicility of the molecule is improved by having 8 units of PEG. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG8-acid has an alkyne group and an acid group. The acid group can derivatize amine-containing molecules in the presence of activators such as EDC or HATU. The alkyne group can react with azides via copper catalyzed Click Chemistry reactions. The PEG units help increase the solubility of the molecule in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG10-alcohol is a heterobifunctional PEG linker which enables Click Chemistry reactions with azide-bearing biomolecules; copper catalyst is needed. The hydrophilic PEG units increase aqueous solubility. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Acid-PEG25-NHS ester is a PEG linker containing a carboxylic acid and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. 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. 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.

N-Me-N-bis(PEG4-t-butyl ester) is a PEG linker containing a methylamine group and a t-butyl ester. The hydrophilic PEG spacer increases solubility in aqueous media. The methylamine group is reactive with carboxylic acids, carbonyls (ketone, aldehyde) etc. The t-butyl protected carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG10-t-butyl ester is a crosslinking reagent that can react with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry reactions. The carboxyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
