Evaluation and comparison of SYBR Green I Real-Time PCR and TaqMan Real-Time PCR methods for quantitative assay of Listeria monocytogenes in nutrient broth and milk [PDF]

open access: yes, 2012
Specific traditional plate count method and real-time PCR systems based on SYBR Green I and TaqMan technologies using a specific primer pair and probe for amplification of iap-gene were used for quantitative assay of Listeria monocytogenes in seven ...

The performance of semi-quantitative differential PCR is similar to that of real-time PCR for the detection of the MYCN gene in neuroblastomas

open access: yesBrazilian Journal of Medical and Biological Research, 2009
Amplification of the MYCN gene in neuroblastomas is a potent biological marker of highly aggressive tumors, which are invariably fatal unless sound clinical management is applied. To determine the usefulness of semi-quantitative differential PCR (SQ-PCR)

Development of a Real-Time Quantitative PCR Based on a TaqMan-MGB Probe for the Rapid Detection of Theileria haneyi

open access: yesMicroorganisms, 2023
Equine piroplasmosis (EP) is a parasitic disease caused by Theileria equi (T. equi), Babesia caballi (B. caballi) and Theileria haneyi (T. haneyi). This disease is considered to be reportable by the World Organization for Animal Health (WOAH).

Investigations into the utility of real-time PCR for the detection, quantitation and characterisation of clinically relevant viruses [PDF]

open access: yes, 2003
The use of PCR as a tool for the diagnostic virology and viral research laboratories has greatly increased in recent years, however the use of conventional PCR and amplicon detection systems can be a complex and relatively slow process that increases the

The prognostic impact of EGFR, ErbB2 and MET gene amplification in human gastric carcinomas as measured by quantitative Real-Time PCR [PDF]

open access: yes, 2015
Purpose: Identification of critical genes which play pivotal roles in controlling tumor growth and survival will establish the basis for developing therapeutic targets. In this study, we focused on frequencies of EGFR, ErbB2 and MET gene amplification in

Simulation of between repeat variability in real time PCR reactions [PDF]

open access: yes, 2012
While many decisions rely on real time quantitative PCR (qPCR) analysis few attempts have hitherto been made to quantify bounds of precision accounting for the various sources of variation involved in the measurement process.

Development of a droplet digital PCR method for detection of porcine circovirus 4

open access: yesBMC Veterinary Research, 2023
Background Porcine circovirus 4 (PCV4), a newly emerging virus that was first discovered in 2019, may pose a potential threat to the pig industry. Droplet digital PCR (ddPCR) is an absolute quantitative method that has high sensitivity and accuracy.

Differential cytokine responses following Marek's disease virus infection in chicken genotypes differing in resistance to Marek's disease [PDF]

open access: yes, 2003
The production of cytokine mRNAs, in addition to viral DNA, was quantified by real-time quantitative reverse transcription-PCR (RT-PCR) (cytokines) or PCR (virus) in splenocytes during the course of Marek's disease virus (MDV) infection in four inbred ...

Differential quantification of CYP2D6 gene copy number by four different quantitative real-time PCR assays [PDF]

open access: yes, 2010
Copy number variations (CNVs) in the CYP2D6 gene contribute to interindividual variation in drug metabolism. As the most common duplicated allele in Asian populations is the nonfunctional CYP2D6*36 allele, the goal of this study was to identify CNV ...
