An oligonucleotide microarray for multiplex real-time PCR identification of HIV-1, HBV, and HCV.

We describe a novel microarray-based approach for simultaneous identification and quantification of human immunodeficiency virus type 1 (HIV-1) and hepatitis B and C viruses (HBV and HCV) in donor plasma specimens. The method is based on multiplex real-time RT-PCR performed within the microarray hydrogel pads. Double-stranded amplification products are simultaneously detected using nonspecific SYBR Green I dye due to the reaction run in separate pads bearing 5'-immobilized specific primers.
