PEG

Azide-PEG4-Tos is a heterofunctional crosslinker containing an azide (N3) group and a tosyl group. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The tosyl group is a good leaving group for nucleophilic substitution reactions. PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Trityl-PEG10-azide is a PEG linker containing an azide group and a trityl protected ester. Trityl group can be removed under acid conditions or hydrogenolysis. 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.

Azido-PEG8-t-butyl ester is a click chemistry compound conpprising an azide group and a t-butyl ester moiety. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

3-(2-bromoacetamido)propanoic acid NHS ester is a PEG linker containing a bromide group and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. 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-PEG6-bromide is a PEG linker containing a bromide group. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

3-(2-bromoacetamido)propanoic acid is a compound containing a bromide group and a terminal carboxylic acid. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. 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.

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.
