The deoxytetradecamer d(AAAACGACGGCCAG) has been shown to be an excellent universal primer for sequence determination of DNA cloned into the bacteriophage M13 mp7, mp8, and mp9 series. This new primer offers several advantages over others currently available and it has been used to define the cloning of Hinf I fragments of bacteriophage S13 DNA into the Eco RI site of M13 mp7, utilizing the hom...

The non-coding region of the mitochondrial genome provides an attractive target for human forensic identification studies. Two hypervariable (HV) regions, each approximately 250-350 bp in length, contain the majority of mitochondrial DNA (mtDNA) sequence variability among different individuals. Various approaches to determine mtDNA sequence were evaluated utilizing highly sensitive infrared (IR...

The UniPrime2 web server is a publicly available online resource which automatically designs large sets of universal primers when given a gene reference ID or Fasta sequence input by a user. UniPrime2 works by automatically retrieving and aligning homologous sequences from GenBank, identifying regions of conservation within the alignment, and generating suitable primers that can be used to ampl...

A novel primer designed to improve the specificity of PCR amplification, called the annealing control primer (ACP), comprises a tripartite structure with a polydeoxyinosine [poly(dI)] linker between the 3' end target core sequence and the 5' end nontarget universal sequence. We show that this ACP linker prevents annealing of the 5' end nontarget sequence to the template and facilitates primer h...

We attempted to develop a PCR-based marker that detects various segments of rye chromosome incorporated into wheat. We designed three sets of PCR primers based on the nucleotide sequence data of a rye repetitive sequence previously reported. One of the primer sets amplified a clear ca. 1.4 kb fragment in a rye cultivar but not in any form of wheat, diploid, tetraploid or hexaploid. We used this...

Four primer systems, amplifying fragments of the gene coding for the small ribosomal subunit (18S rRNA) were characterised with pure cultures of 65 medically relevant fungal species plus two mushrooms. A primer cocktail (TR1/CA1-TR2/AF2) amplified 59 of 67 fungal species; the universal fungal primer 1 (UF1) in combination with the eukaryotic primers S3 or EU1 amplified 64 and 65 of 67 fungal sp...

The determination of unknown DNA sequences around a known locus has important applications in molecular genetics, specifically in genomic walking and genome mapping. Several PCR-based methods have been reported to address this issue, but they often involve multiple, time-consuming steps. We have previously described a technique known as restriction site PCR (RS-PCR) that allows sequence acquisi...

The molecular features of Pseudomonas syringae pv. actinidiae strains isolated in Korea were compared with strains isolated in Japan and Italy. Sequencing of eight P. syringae pv. actinidiae and three P. syringae pv. theae strains revealed a total of 44 single nucleotide polymorphisms across 4,818 bp of the concatenated alignment of nine genes. A multiplex PCR assay was developed for the detect...

PURPOSE The aim of the study was to evaluate the effect of 3 silicone primers and 3 surface characterization of acrylic resin surface on bond strength between silicone elastomer and acrylic resin. MATERIALS AND METHODS 96 Cosmesil silicones bonded to heat-curing acrylic resin were fabricated with the dimension of 75 × 10 × 3 mm. The 3 primers used in this study were G611 platinum primer, A-33...
