TAMRA-Azide-PEG-biotin 

TAMRA-Azide-PEG-biotin is a dye derivative of TAMRA (HY-135640). TAMRA-Azide-PEG-biotin contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. Strain-promoted alkyne-azide cycloaddition (SPAAC) can also occur with molecules containing DBCO or BCN 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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
