(4E)-TCO-PEG4-DBCO Usage And Synthesis

Description

TCO-PEG4-DBCO is a heterobifunctional click chemistry reagent containing a TCO and a DBCO moiety. TCO group specifically and efficiently reacts with terrahydrazine at fast speed. DBCO is very reactive toward Azide through copper free click chemistry, the PEG spacer increases the aqueous solubility of the reagent.
