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 ... WebSep 24, 2024 · Although these labelling techniques are very simple and efficient for adjoining biotin to avidin conjugates, identical biotin binding-site of avidin may raise some issues of undesirable conjugation of biotinylated complexes due to its random cross-linking [26]. Thus, we modified biotin binding sites by attaching four distinct DNAs to TAv rather ...
