TAMRA-PEG4-methyltetrazine 

TAMRA-PEG4-methyltetrazine is a dye derivative of TAMRA (HY-135640) containing 4 PEG units. TAMRA-PEG4-methyltetrazine contains a Tetrazine group that can undergo an inverse electron demand Diels-Alder reaction (iEDDA) with molecules containing TCO groups.

PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins^[1].
