Medchemexpress LLC Biotin-PEG2-azide | 1910803-72-3 | 97.0% | 500 MG
Biotin-PEG2-azide is a PEG-based PROTAC linker utilized in the synthesis of PROTACs. It functions as a click chemistry reagent due to its Azide group, enabling it to participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with alkyne-containing molecules. Additionally, it can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules possessing DBCO or BCN groups.
- PEG-based PROTAC linker
- Click chemistry reagent
- Contains an azide group for CuAAc reactions
- Can undergo SPAAC reactions with DBCO or BCN groups
Nacalai USA Inc TURBOTEV (TEV PROTEASE) 2MG/ML
