How does a nested rt-pcr assay work
WebApr 12, 2024 · However, another study indicated that a real-time-PCR-based assay showed that it is superior to the BDG method. The detection of very-low-birth-weight preterm neonatal patients’ infection showed the sensitivity and specificity of the real-time PCR were 87.5% and 81.6%, respectively, while for the BDG method they were 75.0% and 64.6% [ 14 ]. WebRT-qPCR can be performed in a one-step or a two-step assay ( Figure 1, Table 1). One-step assays combine reverse transcription and PCR in a single tube and buffer, using a reverse transcriptase along with a DNA …
