Using dd-PCR and RT-qPCR technology, dynamic BCR/ABL transcripts were detected in 13 CML patients who discontinued TKI treatment after sustaining undetectable BCR-ABL levels for a median time of 25 months. The results showed that in 13 patients, only 2 cases (22.2%) of 9 patients who executed planned discontinuation achieved TFR within 12 months. In the first 6 months, the detection rate of

Everyone’s needs are unique and that’s why we have expanded the Applied Biosystems QuantStudio family of real-time PCR and digital PCR systems. Now you can pick the qPCR platform that best fits your research requirements—find your fit today. Q-bond technology and an optimized master mix promote fast, multiplex real-time RT-PCR, not only on fast cyclers with short ramping times, but also on standard cyclers. The combination of a hot start and a unique PCR buffer system in the ready-to-use master mix ensures highly sensitive qPCR on any real-time cycler without the need for optimization. QPCR Assay Design Considerations •Initial optimization efforts should identify good control or standard RNA or DNA that you can rely upon throughout data generation •Generate a range of acceptable QPCR performance data •Controls should dictate what data is good or bad •Practice setting up assay, its not a trivial task Blood. The Abbott RealTime FDA approved CMV assay uses real-time PCR fluorescent detection for the quantitation of CMV DNA in plasma. The PCR assay amplifies two select targets of conserved regions of the CMV genome, UL34 and UL80.5 genes.

The QXDx BCR-ABL %IS Kit and ddPCR technology have some inherent advantages over conventional RT-PCR. This includes scalable sensitivity with an improved LOD (1 to 2 logs) and less sensitivity to/ impact by amplification efficiency compared to RT-PCR.

A nested single-copy locus-based quantitative PCR (qPCR) assay and a multicopy locus-based qPCR assay were developed to estimate endophytic biomass of fungal root symbionts belonging to the Phialocephala fortinii sensu lato- Acephala applanata species complex (PAC). Both assays were suitable for estimation of endophytic biomass, but the nested assay was more sensitive and specific for PAC. For Q’s miniature speaker-size and 4.5 pound weight make it the most portable and versatile qPCR machine on the market without ever needing to calibrate. Q also provides scalability as each qPCR machine can process up to 48 samples per run and up to 10 Q’s can be connected to a single computer wirelessly via bluetooth enabling up to 480 samples Real time PCR (quantitative PCR, qPCR) is now a well-established method for the detection, quantification, and typing of different microbial agents in the areas of clinical and veterinary diagnostics and food safety. Although the concept of PCR is relatively simple, there are specific issues in qPCR that developers and users of this technology must bear in mind.

Most applications of polymerase chain reaction focus on its utility as a way to turn a small amount of DNA into a larger amount of DNA. Xpert BCR-ABL Ultra is a quantitative test for BCR-ABL major breakpoint (p210) transcripts that provides highly sensitive and on-demand molecular results. Based on the innovative GeneXpert ® technology, Xpert BCR-ABL Ultra automates the entire test process including RNA isolation, reverse transcription, and fully-nested real-time PCR of BCR BCR-ABL / GUSB. ratio is calculated.
