UNLABELLED Designed degenerate primers unlike conventional primers are superior in matching and amplification of large number of genes, from related gene families. DPPrimer tool was designed to predict primers for PCR amplification of homologous gene from related or diverse plant species. The key features of this tool include platform independence and user friendliness in primer design. Embedde...

MOTIVATION DNA microarray is a powerful high-throughput tool for studying gene function and regulatory networks. Due to the problem of potential cross hybridization, using full-length genes for microarray construction is not appropriate in some situations. A bioinformatic tool, PRIMEGENS, has recently been developed for the automatic design of PCR primers using DNA fragments that are specific t...

sequencing of a part of the amelogenin gene. This gene is lecated on the X and Y chromosomes, and there are 54 nucleotide de]etions on the Y chromosome-specific gene. Forty-seven (26 ma]e and 21 female) DNA samples and 23 (13 ma}e and 1O female) DNA samples, respectively extracted from white blood cells and hairs ofJapanese black bears were analyzed, The primers SE47 and SE48 from this X-Y homo...

Amplification of DNA sequences using the polymerase chain reaction (PCR) has become a powerful experimental tool for molecular biologists (1, 2). The cloning of amplified products is usually achieved through either blunt end ligations, or the incorporation of restriction enzyme sites into the PCR primers. However, the former process is inefficient and the latter requires linkage of non-homologo...

A polymerase chain reaction (PCR) method was developed for the detection of rodent coronaviruses in biological material by using reverse transcriptase and two primers which flanked an M gene sequence of 375 bp. PCR detected all of 11 different strains of mouse hepatitis virus (MHV) as well as rat sialodacryoadenitis virus but not bovine coronavirus or human coronavirus strains OC43 and 229E. Th...

NBS-LRR-type disease resistance gene-like cDNA, induced by salicylic acid (SA) was cloned from rye Secalecereale L. (2n = 14RR) var. Petkus, which has rust genes such as Lr26, Sr31 andRr9. We designed primers based on the NBS region and performed PCR using Petkus genomic DNA a template. Next, we TA-cloned 532-bp fragment containing five homologous amino sequences in region. The SA-treated showe...

PCR products of 1.8 kb were generated with DNAs from all Escherichia coli H7 strains tested by using oligonucleotide primers which flank the fliC gene. Three RsaI digestion profiles of these PCR products were evident on agarose gels; the first occurred with serotype O55:H7, O157:H7, or nonmotile (NM) strains, the second occurred with serotype O1:H7 and O18:H7 strains, and the third occurred wit...

BACKGROUND The invention of the Genome Sequence 20 DNA Sequencing System (454 parallel sequencing platform) has enabled the rapid and high-volume production of sequence data. Until now, however, individual emulsion PCR (emPCR) reactions and subsequent sequencing runs have been unable to combine template DNA from multiple individuals, as homologous sequences cannot be subsequently assigned to th...
