Propargyl-PEG4-t-butyl ester enables the formation of a stable triazole linkage with azide compounds or biomolecules via copper catalyzed Click Chemistry reactions. The t-butyl protected carboxyl group can be hydrolyzed under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG4-acid is a PEG reagent with an alkyne and a terminal carboxylic acid. The carboxylic acid reacts with primary amine groups with the help of activators (e.g. EDC, or HATU). The 4-unit PEG spacer increases hydrophilicity. The alkyne can participate in copper-catalyzed Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bromoacetamido-PEG5-azide is a heterobifunctional crosslinking reagent. The bromide (Br) is a very good leaving group for nucleophilic substitution. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Boc-PEG4-alcohol is a PEG linker containing a hydroxyl group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. 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.

m-PEG4-benzaldehyde is a small molecule PEG linker containing a terminal benzaldehyde moiety that can react with primary amine groups. PEG4 armr increases the solubility of compounds in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG8-NHS ester is a PEG linker containing an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG12-NHS ester is a PEG linker containing an NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG12-acid is a PEG linker containing a terminal carboxylic acid. 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 hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
