Abstract: Objective To develop an oligonucleotide microarray for fast detection of human immunodeficiency virus (HIV).Methods With complete genome sequence of HIV-1 subtype B (U26942) as the target sequence and bioinformatics software such as DNAClub, Oligo6.0, BLAST, Alignment, oligonucleotide probes of high specificity with identical length and similar melting temperature (Tm) were designed and synthesized. Oligonucleotide microarray was prepared using Cartesian Microarrayer. Using the plasmids of HIV-1 subtype B(U26942), C(U46016), F(AF075703), G(AF061640) and restriction display technique, Cy3-labeled HIV DNA fragments were amplified and the hybridization results were scanned and analyzed with Array-Pro.Results and Conclusion Twenty-two optimized oligonucleotide microarray probes were obtained and used to prepare the oligonucleotide microarray for further screening studies. The microarray prepared significantly enhanced the sensitivity, reliability and speed of DNA assay, and possesses the potential for application in clinical setting.
