ABSTRACT
<p><b>OBJECTIVE</b>To study if quantum dots fluorescent probes can be applied to detect P53 protein and Bcl-2 protein in tissue of human tongue squamous cell carcinoma.</p><p><b>METHODS</b>By indirect immunofluorescence assay the same particle size quantum dots fluorescent probes were applied to detect P53 protein and Bcl-2 protein respectively. Different particle size quantum dots fluorescent probes were applied to detect P53 protein and Bcl-2 protein simultaneously in paraffin-embedded tissue section of human tongue squamous cell carcinoma under fluorescent microscope.</p><p><b>RESULTS</b>P53 protein and Bcl-2 protein can be combined with quantum dots fluorescent probes and specific fluorescene can be observed with ultraviolet light excited. P53 protein was mainly distributed in the nucleus, and Bcl-2 protein major in the cytoplasm. P53 protein and Bcl-2 protein can be combined with different particle size quantum dots fluorescent probes respectively in the same paraffin-embedded tissue section of human tongue squamous cell carcinoma and two kinds of fluorescene can be observed.</p><p><b>CONCLUSION</b>Quantum dots fluorescent probes can be applied to detect two kinds of specific protein in paraffin-embedded tissue section of human tongue squamous cell carcinoma.</p>
