The demand for high-throughput DNA profiling has increased with the introduction of national DNA databases and has led to the development of automated methods of short tandem repeat (STR) profile production; however, a potential bottleneck still exists at the gel electrophoresis stage. Capillary electrophoresis sequencers capable of processing 96 samples with considerably reduced manual interve...

As part of a large international project for standardization of PCR (Food-PCR; www.pcr.dk), a multiplex, multiplatform, ready-to-go enrichment followed by a real-time PCR method, including an internal amplification control, was developed for detection of food-borne thermotolerant campylobacters in chickens. Chicken rinse samples were enriched in Bolton broth for 20 h, a simple and rapid (1-h) r...

BACKGROUND The aim of this study was to compare the ABI PRISM 7700 Sequence Detection System and the LightCycler to develop a quantitative real-time PCR assay for the detection of human cytomegalovirus (HCMV) DNA suitable for routine hospital application. METHODS We used one exonuclease probe and five different hybridization probe sets as sequence-specific fluorescence detection formats. For ...

A method is described that uses the ABI PRISM 310 genetic analyzer in conjunction with custom-designed software to identify and classify RAPD products. This methodology will also work well with AFLPs and microsatellite analyses. The methodology uses the ABI PRISM 310's high-throughput (> 500 samples per week) capabilities and in-lane molecular weight standards to efficiently separate and size D...

Fluorescently labeled size standards are indispensable for genotyping via an automated DNA sequencer. Microsatellites, amplified fragment-length polymorphisms (AFLPs), single nucleotide polymorphisms (SNPs), and random amplified polymorphic DNA (RAPD) can all be assayed on platforms such as the ABI Prism® 377 DNA Sequencer or the ABI Prism 3100-Avant Genetic Analyzer (both from Applied Biosyste...

The aim of this study was to evaluate the use of Locked Nucleic Acids (LNA) probes in 5'-nuclease PCR, by comparison with Minor Groove Binder (MGB) probes routinely practiced in laboratories on ABI Prism 7700. The comparison was made using a collection of Staphylococcus aureus strains that have already been characterized by MGB 5'-nuclease PCR assays in a previous study [Mol Cell Probes, submit...

DNA typing with short tandem repeat (STR) markers is now widely used for a variety of applications including human identification. Capillary electrophoresis (CE) instruments, such as the ABI Prism 310 and ABI 3100 Genetic Analyzers, are the method of choice for many laboratories performing STR analysis. This review discusses issues surrounding sample preparation, injection, separation, detectio...

In our previous population study, we have used twelve Y-chromosomal short tandem repeats loci incorporated in the PowerPlex Y System to determine Y-STR diversity in B&H human population. With intent to obtain additional verification of the previously obtained results as well as to establish specific reference for a local B&H population, we have decided to test DNA samples collected from 100 unr...

We have developed a real-time quantitative PCR assay to measure the concentration of DNA extracted in forensic biological traces. Its rapid and sensitive results were obtained in less than 4 hours. This real-time quantification can be performed on the ABI Prism 7700 Sequence Detector using the fluorogenic probe in a TaqMan assay. We suggest a protocol that will be able to detect and quantitate ...
