For the detection of human immunodeficiency virus (HIV), ultra-rapid real-time PCR methods were developed. The target DNA sequences were used 495 bp HIV-1-specific env gene (gi_1184090) and 294 bp HIV-2-specific env gene (gi_1332355). Ultra-rapid real-time PCR was peformed by $Genspector^{TM}$ (Samsung, Korea) using microchip-based, $6\;{\mu}l$ of reaction volume with extremely short running time in only 2 steps (denaturation, annealing/extension) in each cycle of PCR. Total reaction for 30 cycled ultra-rapid PCR detection including melting temperature analysis was completed in 7 min and 30 sec. The HIV-1-specific 117 bp-long or HIV-2-spe-cific 119 bp-long PCR products were successfully amplified from the minimum of template, $2.3{\times}10^3$ copies of each euv gene using 30 cycled two-steps ultra-rapid PCR. This kind of ultra-rapid real-time PCR method would be useful not only for the rapid-detection of HIV, but also rapid-detection of other pathogens.

For the detection of Human Immunodeficiency Virus (HIV), multiple and ultra-rapid real-time PCR methods were developed. The target DNA sequences were deduced from HIV-1 specific 495bp partial env gene (gi_1184090) and from HIV-2 specific 294 bp partial env gene (gi_1332355), and were synthesized by using PCR-based gene synthesis on the reason of safety. Ultra-rapid real-time PCR was performed by $Genspector^{TM}$ using microchip-based, $1\;{\mu}l$ of reaction volume with extremely short time in each 3 step in PCR. The detection including DNA-amplification and melting temperature analysis was completed inner 15 minutes. The HIV-1 specific 117 bp-long and HIV-2 specific 119 bp-long PCR products were successfully amplified from minimum of template,2.3 molecules of each env gene. This kind of real-time PCR was designated as ultra-rapid real-time PCR in this study and it could be applied not only an alternative detection method against HIV, but also other pathogens using PCR-based detection.
