Abstract:
:We describe a novel technology for detecting nucleic acids: Probe Alteration Link Self-Assembly Reactions (PALSAR). PALSAR comprises DNA self-assembly of pairs of short DNA probes formed by alternate hybridization of three complementary regions in a pair of honeycomb probes (HCPs). Self-assembly occurs at designated salt concentrations and reaction temperatures and requires no enzymes. We prepared pairs of HCPs to detect mRNAs encoded by the GAPDH gene β-actin (BA) gene, CD3D gene, CD4 gene, major vault protein (MV) gene and the signalling lymphocytic activation molecule-associated protein (SAP) gene, and succeeded in quantitatively detecting these mRNAs. PALSAR could detect mRNA directly without synthesizing cDNA. Moreover, multiple mRNAs could be detected simultaneously in a single reaction tube and there was a good correlation between the results obtained PALSAR and those by real-time PCR.
