Compared to indirect methods such as a secondary fluorescently labeled antibody, attaching fluorescent dyes directly to the antibody offers unique advantages:
Quicker and more reproducible results
Suitable for multi-protein complexes
No need for secondary antibodies
No disturbance to epitope recognition
Enhanced robustness
Low batch-to-batch variation
