| Abstract: | Objective To prepare microarray for detection of yellow fever virus(YFV). Methods According to the sequence of YFV genome, 22 oligonucleotide probes were designed by using bioinformatics software. DNA fragments were prepared from pasmid hosting the full length of YFV genome. The DNA fragments were labeled and amplified by the restriction display technology with Cy3-universal primer. After hybridization, microarrays were scanned and analyzed. Results Positive signals could be detected with the YFV oligonucleotide probes, while the negative signals were detected with negative and blank controls. Conclusion Microarray technology provides an efficient alternative for the detection of yellow fever virus. |
