Chemical. CAS 1239-45-8. Formula C21H20BrN3. MW 394.31. Synthetic. Ethidium bromide EtBr is the most commonly used nucleic acid stain for PAGE or agarose gel electrophoresis. The fluorescence of EtBr increases 21-fold upon binding to double-stranded RNA and 25-fold on binding double-stranded DNA so that destaining the background is not necessary with a low stain concentration 10 µg/ml. Ethidium bromide has been used in a number of fluorimetric assays for nucleic acids. Ethidium bromide intercalates double-stranded DNA and RNA and acts as a frameshift mutagen. It confers a deep red stain to DNA by acting as an intercalating agent between the starch bases. It has been shown to bind to single-stranded DNA although not as strongly and triple-stranded DNA. Because of its ability to bind to DNA, EtBr is an inhibitor of DNA polymerase. It can be used in conjunction with acridine orange to differentiate between viable, apoptotic and necrotic cells.

Azido-PEG10-amine is a PEG-based PROTAC linker utilized in the synthesis of PROTACs. It functions as a click chemistry reagent, containing an Azide group that allows it to participate in copper-catalyzed azide-alkyne cycloaddition reactions (CuAAc) and strain-promoted alkyne-azide cycloaddition (SPAAC) reactions. PROTACs themselves are designed to exploit the intracellular ubiquitin-proteasome system for the selective degradation of target proteins.

• Functions as a click chemistry reagent
• Contains an azide group
• Participates in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions
• Engages in strain-promoted alkyne-azide cycloaddition (SPAAC) reactions
• Utilized in the synthesis of PROTACs
