TL;DR: A multiplex PCR was developed for the detection of the following genes characteristic of diarrhoeagenic Escherichia coli, and was a faster, more sensitive, less expensive and less laborious diagnostic procedure than DNA hybridisation.

TL;DR: Simple DNA extraction without the use of phenol, followed by a rapid PCR procedure optimised for multiplex amplification of loci SC8132X, YOR267C and SCPTSY7 and band pattern analysis of the fragments generated by agarose and polyacrylamide gel electrophoresis, has allowed for strain identification among a panel of 30 tested commercial wine strains.

TL;DR: A method using polymerase chain reaction (PCR) was designed for the detection of genetically modified maize, and three insect-resistant GM-maize lines were distinguishable on the basis of the expected lengths of their amplicons.
Abstract: A method using polymerase chain reaction (PCR) was designed for the detection of genetically modified maize (GM-maize). There are four lines of GM-maize imported from the United States, and the presence of recombinant deoxyribonucleic acid (DNA) in the maize could be detected with four pairs of specific oligonucleotide primers designed from the sequences of the newly introduced genes. The maize zein gene was also detected as an internal control. This method allows specific detection of each of Bt11, Event176, MON810 and LIBERTY by using pairs of specific primers designed to amplify a segment including part of the exogenously introduced sequence and part of the intrinsic maize sequence. The detection sensitivity was about 0.05% for Event176, MON810 and LIBERTY, and about 0.01% for Bt11. To distinguish among three insect-resistant GM-maize lines, we designed a multiplex PCR method. These three GM-maize lines were distinguishable on the basis of the expected lengths of their amplicons.

TL;DR: The data illustrated here show that the multiplex PCR technique is useful for screening TCRBV usage and can be easily adapted for analysis of clonal composition in T-cell populations.
Abstract: The selection of various T-cell receptor (TCR) gene families and complex rearrangements during intra-thymic differentiation provide the basis for the expression of antigen specificity by mature T cells. TCR beta variable (TCRBV) transcripts can be identified by RT-PCR, but multiple reactions are required to detect all genes of the TCRBV subfamilies. We describe here a multiplex PCR method that amplifies 46 functional genes comparing 23 TCRBV families in 5 reactions where each reaction contains 4 to 7 specific primers together with a single fluorescence-tagged TCR beta constant region primer. Between 8 and 10 distinct subtypes within each of the 23 TCRBV families can be identified by analysis of the CDR3 length. Multiplex PCR products isolated from agarose gels can be subjected to direct sequencing for confirmation and definitive clonotyping if necessary. The data illustrated here show that the multiplex PCR technique is useful for screening TCRBV usage and can be easily adapted for analysis of clonal composition in T-cell populations.
