Flamma® Fluors for Click Chemistry
The most widely utilized click chemistry is 1,3-dipolar cycloaddition between an azide and an alkyne to produce 1,4-disubstituted 1,2,3-triazole. There are two types of 1,3-dipolar cycloaddition methods: copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) and strain-promoted azide-alkyne cycloaddition (SPAAC). BioActs offers Flamma® Fluors Alkyne dyes for CuAAC, Flamma® Fluors ADIBO products for SPAAC and Flamma® Fluors Azide dyes for both CuAAC and SPAAC.
