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)

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

Detection and quantification of Verticillium dahliae and V. longisporum by droplet digital PCR versus quantitative real-time PCR

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Vascular wilt, caused by Verticillium dahliae and V. longisporum, limits the quality and yield of agricultural crops. Although quantitative real-time PCR (qPCR) has greatly improved the diagnosis of these two pathogens over traditional, time-consuming ...

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

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 ...

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.

Evaluation and validation of reference genes in Cymbidium faberi for real-time quantitative PCR

open access: yesBioTechniques, 2022
For all organs at all Cymbidium faberi stages, ACT, UBQ3 and GAPDH can be selected as reference genes. For organs of the vegetative stage, UBQ2 and UBQ3 can be chosen for analysis of normalized gene expression. For the bud stage, ACT and UBQ3 can be used
