Noninvasive samples have proved useful in genotyping studies of free-ranging mammals. However, potential genotyping errors associated with such samples dictate the need for validation studies. This pilot study demonstrates the use of dolphin faeces in multilocus microsatellite genotyping studies. An empirical approach to calculating the rate of genotyping error was applied to data from matched ...

Abstract The use of museum specimens held in natural history repositories for population and conservation genetic research is increasing tandem with the massively parallel sequencing technologies. Short Tandem Repeats (STRs), or microsatellite loci, are commonly used markers wildlife studies. However, they traditionally suffered from a host issues including length homoplasy, high costs, low thr...

As of June 2009, 361 genome-wide association studies (GWAS) had been referenced by the HuGE database. GWAS require DNA from many thousands of individuals, relying on suitable DNA collections. We recently performed a multiple sclerosis (MS) GWAS where a substantial component of the cases (24%) had DNA derived from saliva. Genotyping was done on the Illumina genotyping platform using the Infinium...

Selective genotyping concerns the genotyping of a portion of individuals chosen on the basis of their phenotypic values. Often individuals are selected for genotyping from the high and low extremes of the phenotypic distribution. This procedure yields savings in cost and time by decreasing the total number of individuals genotyped. Previous work by Darvasi et al. (1993) has shown that the power...

BACKGROUND We evaluated the performance of two different array-based techniques, a bead-based multiplex genotyping method (LQ; digene HPV Genotyping LQ Test, QIAGEN, Germany) and a DNA chip-based method using peptide nucleic acid probes (PANArray; PANArray HPV Genotyping Chip, Panagene, Korea), for detection of human papillomavirus (HPV) and genotyping of high-risk (HR) or probable high-risk (P...

Objectives: To identify and to characterize of methicillin-resistant Staphylococcus aureus (MRSA) isolates collected from food (n=43), handler (n=8), clinical samples (n=15). Methods: Genotyping was applied for the purposes epidemiological investigation source tracking these isolates. Pulsed field gel electrophoresis (PFGE) performed using restriction endonucleases SmaI. Findings: PFGE analysis...

Next-generation sequencing (NGS) approaches are widely used in genome-wide genetic marker discovery and genotyping. However, current NGS approaches are not easy to apply to general outbred populations (human and some major farm animals) for SNP identification because of the high level of heterogeneity and phase ambiguity in the haplotype. Here, we reported a new method for SNP genotyping, calle...

High-throughput genotyping approaches are being developed to meet the demands of pharmacogenomics, where numerous individuals are studied with thousands of single nucleotide polymorphism (SNP) markers. All non-gel-based genotyping approaches achieve allelic discrimination by one of four mechanisms: allele-specific hybridisation, allele-specific primer extension, allele-specific oligonucleotide ...
