Quantum dot-linked immunosorbent assay. (a) The fluorescent observation of microtiter wells with QD-linked antibodies on a UV lamp tray. (b) The fluorescent observation of microtiter wells after washing with TBS and filling with deionized water on the UV lamp tray. (c) Observation under a UV filter of a fluorescent microscope gives a blue color. (d) Observation under a blue excitation filter gives a green color and confirmed the binding of antibodies with antigen.
