Long single-stranded DNAs and RNAs possess considerable secondary structure under conditions that support stable hybrid formation with oligonucleotides. Consequently, different oligomeric probes can hybridize to the same target with efficiencies that vary by several orders of magnitude. The ability to enzymatically generate structure-free single-stranded(More)
The polymerase chain reaction (PCR) is widely used for applications which require a high level of specificity and reliability, such as genetic testing, clinical diagnostics, blood screening, forensics and biodefense. Great improvements to PCR performance have been achieved by the use of Hot Start activation strategies that aim to prevent DNA polymerase(More)
A straightforward enzymatic protocol for converting regular DNA into pseudo-complementary DNA could improve the performance of oligonucleotide microarrays by generating readily hybridizable structure-free targets. Here we screened several highly destabilizing analogs of G and C for one that could be used with 2-aminoadenine (nA) and 2-thiothymine (sT) to(More)
