Although there have been assessments of supermix effects on droplet volume (ddPCR™ Supermix™ for Probes [17–19]; ddPCR™ Supermix™ for Probes (no dUTP) ; QX200™ ddPCR™ Eva Green™ Supermix™ ), all of the studies to date have been focused only on the DG8 manual droplet generator and to the best of our …Apr 2, 2022 · The annealing temperature was varied for the ddPCR assay to determine the optimal conditions. The ddPCR assay was performed in a 20 μL reaction, containing 10 μL of 2 × ddPCR Supermix (Bio-Rad, Co., Ltd., California, USA), 1 μL of plasmid DNA, 1.6 μM (800 nmol/L) each of the primers, and 0.4 μL (200 nmol/L) of the probe. The nanoplate-based technology offers significant benefits over digital droplet PCR (ddPCR). These include: • Fixed partitions prevent variation in size and coalescence • Sealed nanoplates prevent well to well contamination • Faster readout possible due to simultaneous reading of all partitions of a sampleEach ddPCR sample contained 11 μL 2× ddPCR Supermix for Probes (no dUTP) (Bio-Rad, Hercules, CA, USA), 900 nM each primer pair, and 227 nM probe, to which 2 μL first-strand cDNA was added; the final volume was adjusted to 22 μL with sterile ddH 2 O. The droplet counts were analyzed, and absolute gene expression measurements were generated ...Aug 18, 2016 · ddPCR workflow. Preparation of 20 μL ddPCR reactions used 10 μL of 2X ddPCR SuperMix for probes (No dUTP) (Bio-Rad Inc., Hercules, CA), 5–20 ng of gDNA quantified by the Qubit dsDNA high sensitivity assay kit (Thermo Fisher Scientific, Waltham, MA), forward primers (FP) and reverse primers (RP), each at a final C t = 900 nM, and FAM and/or HEX Use this 2x digital PCR supermix for probes (No dUTP) for applications such as mutation detection, copy number analysis, and absolute quantification.

To compare the dynamic range of ddPCR and RT-PCR, serial dilutions of a positive control linear DNA standard of SARS-CoV-2 were tested using primers/probe sets targeting ORF1ab and N of SARS-CoV-2 for both ddPCR and RT–PCR. As shown in Figure 1, the reportable range of ddPCR is 10–5 × 10 4 copies/reaction for both ORF1ab and N …ddPCR Supermix for Residual DNA Quantification is stable at –20°C through the expiration date printed on the labels. Once thawed, it can be stored at 4°C for up to 2 weeks. Repeated freezing and thawing of the supermix is not recommended. Quality Control ddPCR Supermix for Residual DNA Quantification is free of contaminating DNase and RNase. Droplet digital PCR (ddPCR) was performed based on the water–oil emulsion droplet technology, using the ddPCR™ Supermix for Probes and reagents in the QX200™ Droplet Digital™ PCR system (Bio-Rad Laboratories, Hercules, CA) (Dash et al. 2019). For quantification of HIV-1 DNA, the eluted brain DNA was PCR-amplified using Taqman set ...As master mix the ‘ddPCR Supermix for Probes’ (Cat. No. 186-3010, Bio-Rad) was used.
