Biotin Azide Plus is an oxazolidine reagent that integrates azide-biotin click chemistry and a photocleavable linker arm. Biotin Azide Plus not only reacts with biotin thioether to form stable sulfinimide products, but also enables bioconjugation of proteins and DNA through biotin redox-activated chemical labeling technology. Taking advantage of the streptavidin capture and photo-release properties, Biotin Azide Plus effectively facilitates the isolation of lipid-derived electrophile-protein adducts, thus finding wide application in scientific research related to fields such as SKBR3 cancer .
