PEG

Tri(Azide-PEG10-NHCO-ethyloxyethyl)amine is a branched PEG linker with three terminal azide groups. The azide groups enable PEGylation via Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tetra-(amido-PEG10-azide) is a branched PEG linker with four terminal azide groups. The azide groups enable PEGylation via Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Methyltetrazine-PEG9-acid is a stable tetrazines molecule containing a terminal carboxylic acid. The carboxylic acid can react with primary amine groups in the presence of of activators (e.g. EDC, or HATU) to form a stable amide bond. Methyltetrazine enable fast click chemistry with TCO ((trans-cycloctene), methyl group enhances the stability of tetrazine moiety. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
