HIV POC testing by ssDNA coupled with NALF
Poster Jul 31, 2009
A isothermal amplification termed Reverse Transcription Loop Dependant Amplification (RT-LDA) was developed with an affordable nucleic acid lateral flow detection (NALF) system, as one component of a potential POC HIV-1 RNA assay for subtypeC. RT-LDA makes use of a primer design that efficiently converts viral RNA into ssDNA amplicons, in 1 hour at 53ºC. Due to the single stranded nature of the product, the amplicon could be detected using NALF.
When there is a need to quickly analyze samples using a number of different PCR assays, it is likely that optimal conditions for each assay will not be the same. First, different assays often will require different annealing temperatures for their primers. In addition, amplicons may be designed to be of different lengths and therefore require varying durations of the extension step.READ MORE
