英文摘要 | A functionalized gold nanoparticle (gnp) enhanced ultrasensitive immuno-pcr assay (gnp-ipcr on elisa plate), which was modified from the recent developed bio-barcode assay (bca) technique, was developed to detect hantaan virus nucleocapsid protein (hnp). during the assay, the target antigen hnp was captured by a polyclonal antibody coated on elisa microplate wells, followed by adding gnp dually modified with oligonucleotides and a hnp specific monoclonal antibody l13 (mab l13) to form a sandwich immuno-complex. the oligonucleotides on the gnp contained two strands: one as capture dna immobilized on the surface of the gnp through au-s bond and the other as signal amplification dna, which was partially complementary with the capture dna. after the immuno-complex was formed, the signal dna was released by heating, and consequently characterized by pcr/gel electrophoresis and sybr-green real time pcr. the detection limit of this method could reach down to 10 fg/ml for detecting purified hnp in buffers as well as in human serum, which was similar to 7 orders of magnitude more sensitive than that of conventional elisa. the current assay format might be adopted for other proteins that need ultra-high sensitive detection.
