A very sensitive and specific method for the random amplification of whole DNA molecules and genomes ranging from 400 base pairs (bp) to 40 Megabase (Mb) is described. This simple, two step PCR (1-3) strategy utilizes tagged random primers that consist of a pool of all possible 3' sequences for binding to the target DNA and a constant 5' region for the detection of incorporated primers. As litt...
In order to provide feasible primer sets for performing a polymerase chain reaction (PCR) experiment, many primer design methods have been proposed. However, the majority of these methods require a long time to obtain an optimal solution since large quantities of template DNA need to be analyzed, and the designed primer sets usually do not provide a specific PCR product size. In recent years, p...
PURPOSE Noroviruses (NoV) are increasingly recognized as an important cause for acute gastroenteritis, worldwide. Reverse transcription polymerase chain reaction (RT-PCR) and sequencing are the methods of choice for the detection of NoVs, but there is currently no consensus about the primers to be used in these assays. MATERIALS AND METHODS In this study, five published primer sets were evalu...
MOTIVATION The optimization of the primer design is critical for the development of high-throughput SNP genotyping methods. Recently developed statistical models of the SNP-IT primer extension genotyping reaction allow further improvement of primer quality for the assay. RESULTS Here we describe how the statistical models can be used to improve primer design for the assay. We also show how to...
Real-time quantitative polymerase chain reaction (qPCR) is one of the most important methods for analyzing the expression patterns of target genes. However, successful qPCR experiments rely heavily on the use of high-quality primers. Various qPCR primer databases have been developed to address this issue, but these databases target only a few important organisms. Here, we developed the qPrimerD...
Species diversity of metazoan bulk samples can be rapidly assessed using Cytochrome c oxidase I (COI) metabarcoding. However, in cases where only degraded DNA is available, e.g. from poorly conserved museum specimens, eDNA filtered from water or gut content analyses, universal primer sets that amplify only a short COI fragment are advantageous. Using PrimerMiner, we optimised two universal prim...
alpha-l-Threofuranosyl nucleoside triphosphates (tNTPs) are tetrafuranose nucleoside derivatives and potential progenitors of present-day beta-d-2'-deoxyribofuranosyl nucleoside triphosphates (dNTPs). Therminator DNA polymerase, a variant of the 9 degrees N DNA polymerase, is an efficient DNA-directed threosyl nucleic acid (TNA) polymerase. Here we report a detailed kinetic comparison of Thermi...
Archaeal family B polymerases bind tightly to the deaminated bases uracil and hypoxanthine in single-stranded DNA, stalling replication on encountering these pro-mutagenic deoxynucleosides four steps ahead of the primer-template junction. When uracil is specifically bound, the polymerase-DNA complex exists in the editing rather than the polymerization conformation, despite the duplex region of ...
Gene 4 protein (gp4) encoded by bacteriophage T7 contains a C-terminal helicase and an N-terminal primase domain. After synthesis of tetraribonucleotides, gp4 must transfer them to the polymerase for use as primers to initiate DNA synthesis. In vivo gp4 exists in two molecular weight forms, a 56-kDa form and the full-length 63-kDa form. The 56-kDa gp4 lacks the N-terminal Cys(4) zinc-binding mo...
