Biotin conjugation site
WebIn this particular case, K121 is located near the biotin-binding site of streptavidin, close enough for potential proximity-induced site-selectivity. Post-conjugation conditions, DtBio was functionalised with a BODIPY-alkyne for fluorescent labelling via CuAAC. Fluorescence was detected only on K121-containing streptavidin, with none observed ... Web4 Biotin/Streptavidin Conjugation. Biotin/Streptavidin is commonly used when the target of interest is expressed at low levels and cannot be detected using labeled antibodies alone. Biotin is used in two-step detection systems in concert with conjugated streptavidin or avidin. Many biotin molecules can be conjugated to an antibody with the ...
