DBCO STP ester is a water-soluble reagent with a terminal DBCO group and a STP ester group. DBCO STP ester that can be used for the modification of peptides, antibodies, proteins, and other molecules containing the amine group. The STP esters are excellent alternatives to conventional N-hydroxysuccinimide (NHS) esters for coupling reactions in aqueous environments. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. Reagent grade, for research use only.

t-Boc-aminooxy-PEG1-propargyl is a click chemistry PEG linker with a t-Boc-aminooxy group. The propargyl group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The t-Boc aminooxy group can be deprotected under mild acidic conditions and then can react with an aldehyde or ketone group to form a stable oxime linkage. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
