Establishment of Diagnostic Assay for Hantavirus with Microarray Techniques

To establish a rapid, sensitive and specific diagnostic assay for Hantavirus with microarray techniques, specific primers and probes were designed according to the conservative and specific DNA sequence of 76-118 strain and R22 strain. The probes were spotted on glass slides to form microarrays. The Cy3-labled single stranded DNA fragments prepared by dissymmetical PCR were hybridized with the probes on the glass slides. The microarrays were scanned and analyzed with a scanner. The results showed that the DNA microarray could detect the different typed DNA of HTN and SEO with adequate specificity and sensitivity. The developed DNA microarray and techniques might be a very useful method for diagnosis and prevention, and could be widely applied in specific pathogens detection of infectious diseases such as hemorrhagic fever with renal syndrome.
