TCI Biotin-PEG4-Azide (B5546, CAS 1309649-57-7) is a click chemistry reagent featuring a biotin affinity tag linked via a PEG4 spacer to an azide reactive group. It is primarily used for biotinylation of alkyne-modified biomolecules through copper-catalyzed or strain-promoted azide-alkyne cycloaddition reactions. This reagent is ideal for applications in protein labeling, affinity purification, pull-down assays, and various streptavidin-based detection systems.
