Propargyl-PEG4-bromide

Methyltetrazine-PEG23-DBCO is a TCO reactive reagent with a DBCO group and water-soluble PEG spacer. This reagent can be used to convert azido-containing peptides or proteins into tetrazine-modified peptides or protein without catalyst or axillary reagents. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Boc-PEG3)-N-bis-(PEG3-Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane) is a crosslinker consisting of six propargyl groups and a t-Boc protected aminooxy group. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The protected amine can be deprotected under acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research use only.
