Self-reporting PNA/DNA primers for PCR analysis.

open access: yesGenome Research, 2001
We report a new fluorogenic method for sealed-tube PCR analysis using a quencher-labeled peptide nucleic acid (Q-PNA) probe. The Q-PNA hybridizes to a complementary tag sequence located at the 5' end of a 5' fluorophore-labeled oligonucleotide primer ...

Blocking primers to enhance PCR amplification of rare sequences in mixed samples – a case study on prey DNA in Antarctic krill stomachs

open access: yesFrontiers in Zoology, 2008
Background Identification of DNA sequence diversity is a powerful means for assessing the species present in environmental samples. The most common molecular strategies for estimating taxonomic composition depend upon PCR with universal primers that ...

Fungal-specific PCR primers developed for analysis of the ITS region of environmental DNA extracts

open access: yesBMC Microbiology, 2005
Background The Internal Transcribed Spacer (ITS) regions of fungal ribosomal DNA (rDNA) are highly variable sequences of great importance in distinguishing fungal species by PCR analysis.

DNA Metabarcoding Using Indexed Primers: Workflow to Characterize Bacteria, Fungi, Plants, and Arthropods from Environmental Samples

open access: yesDiversity
Environmental DNA from bulk materials can be analyzed to gain an understanding of the bacterial, fungal, plant, and/or arthropod communities present. DNA metabarcoding is widely used to characterize these biological communities, by amplifying “barcode ...

Development of a Species Diagnostic Molecular Tool for an Invasive Pest, Mythimna loreyi, Using LAMP

open access: yesInsects, 2020
The Mythimna loreyi (Duponchel) is one of the well-known invasive noctuid pests in Africa, Australia, and many Asian countries. However, it is difficult to identify the invasive and morphologically similar species, Mythimna separate, which occur at the ...

Comparison of different primes for PCR-based diagnosis of cutaneous leishmaniasis

open access: yesBrazilian Journal of Infectious Diseases, 2011
Objective: The objective of this study was to analyze different primers that are commonly used in epidemiological studies for the detection of Leishmania DNA by PCR, and to compare them to the conventional direct parasite search for American cutaneous ...

Effectiveness of annealing blocking primers versus restriction enzymes for characterization of generalist diets: unexpected prey revealed in the gut contents of two coral reef fish species. [PDF]

open access: yesPLoS ONE, 2013
Characterization of predator-prey interactions is challenging as researchers have to rely on indirect methods that can be costly, biased and too imprecise to elucidate the complexity of food webs.
