PEG

DBCO-PEG8-acid is an analog of DBCO-Acid with hydrophilic PEG linker and a DBCO group. The DBCO groups is commonly used for Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds 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. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG1-NHS Ester is a PEG containing molecule containing an NHS ester moiety that can react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG10-NHS ester is a PEG linker containing an NHS ester. The NHS ester is amine reactive and 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.

DNP-PEG4-DBCO is a PEG linker containing a DNP moiety and a DBCO moiety. DNP is involved in biological applications such as participating in ion transport across membranes. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. The hydrophilic PEG linkers increase the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-PEG15-acid is a PEG linker containing terminal carboxylic acid moieties. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The terminal carboxylic acids can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

3-(Azido-PEG5-amino)propanol is a PEG linker which contains an azide moiety and a terminal hydroxyl group. The azide is commonly used for copper-catalyzed Click Chemistry reactions with alkynes, DBCO and BCN to form triazole linkages. The hydroxyl group can react to further derivatize the compound. The hydrophilic PEG spacer increases the water solubility of compounds in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG6-Ms is a PEG reagent that enables Click Chemistry reactions with azide-bearing compounds or biomolecules; copper is needed as a catalyst. The PEG spacer increases the water solubility of the reagent in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fmoc-N-methyl-PEG4-NHS ester is a PEG linker containing an Fmoc-protected amine and an NHS ester. The hydrophilic PEG spacer increases the water solubility of a compound in aqueous media. The Fmoc protecting group can be removed 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.

m-PEG4-DBCO is a click chemistry reagents which can enable so called copper-free Click Chemistry with azide to form a stable triazole. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
