Objective: Reverse transcriptase loop-mediated isothermal amplification (RT-LAMP) is one of the time-saving, accurate, and cost-effective alternative methods to real-time polymerase chain reaction (RT-PCR). This study aimed identify robustness a colorimetric RT-LAMP assay kit that we developed, detecting SARS-COV-2 viral RNA within 30 minutes using primer set special N gene against RT-PCR, gold...

during 2009-10, real time rt-pcr and conventional rt-pcr techniques used for detecting btvs rna in 310 blood samples. for real time and gel based rt-pcr segment-1 and segment-10 selected as conserve genes to search any btv strains. using these methods, 58 (%18.7) and 14 (%4.5) positive samples were detected among the clinically suspected sheep. sensitivity of both molecular techniques evalua...

We developed a rapid, sensitive, and reproducible assay to quantify Candida albicans ACT1, CDR1, CDR2, ERG11, and MDR1 mRNA using a two-step reverse transcription and LightCycler real-time PCR (RT-LightCycler PCR) method with sequence-specific hybridization probes. We compared RT-LightCycler PCR with Northern hybridization for quantitative analysis of gene expression in isolates with various fl...

PURPOSE Central and local laboratory concordance for hormone receptor measurement is therapeutically important. This study compares estrogen receptor (ER) and progesterone receptor (PR) measured by local laboratory immunohistochemistry (IHC), central IHC, and central reverse-transcriptase polymerase chain reaction (RT-PCR) using a proprietary 21-gene assay. PATIENTS AND METHODS A case-control...

Purpose: Atypical teratoid/rhabdoid tumors (AT/RT) are highly aggressive pediatric malignancies characterized by biallelic inactivation of the SMARCB1 tumor suppressor gene. We searched for novel genomic aberrations by investigating the copy number and expression alterations of let-7a3/let-7b microRNA (miRNA) and correlated these with expression of high-mobility group AT-hook 2 (HMGA2) oncoprot...

PURPOSE The main goal of sentinel lymph node (SLN) detection in head and neck squamous cell carcinomas is to limit neck dissections to pN+ cases only. However, intraoperative + diagnosis cannot be routinely done using the current gold standard, serial step sectioning with immunohistochemistry. Real-time quantitative reverse transcription-PCR (RT-PCR) is potentially compatible with intraoperativ...

The reverse transcription polymerase chain reaction (RT-PCR) is the most sensitive method for the detection of low-abundance mRNA, often obtained from limited tissue samples. However, it is a complex technique, there are substantial problems associated with its true sensitivity, reproducibility and specificity and, as a quantitative method, it suffers from the problems inherent in PCR. The rece...

Genetic modification of human mesenchymal stem cells (MSC) is a powerful tool to improve the therapeutic utility of these cells and to increase the knowledge on their regulation mechanisms. In this context, strong efforts have been made recently to develop efficient nonviral gene delivery systems. Although several studies addressed this question most of them use the end product of a reporter ge...

We established the validity of a quantitative reverse transcription (RT)-PCR assay for the RNA component of human telomerase (hTR), using the TaqMan fluorogenic detection system. Using this assay, we quantified hTR expression in two human pancreatic cancer cell lines, ASPC-1 and MIAPaCa-2. Our results indicated that hTR expression in MIAPaCa-2 was 1.99-fold higher than that in ASPC-1 cells. Thi...
