Utilizing proven Applied Biosystems OptiFlex technology and VeriFlex blocks, the QuantStudio 3 system offers improved data accuracy and sensitivity for a broad range of genomic applications, such as analyses of gene expression, microRNAs and noncoding RNAs, SNP genotyping, copy number variation, mutation detection, drug metabolism enzymes, and protein expression.

Precise quantification with 1.5-fold discrimination

Figure 1. The QuantStudio 3 and 5 systems provide sensitive detection and high-confidence target discrimination down to 1.5-fold differences. (A) Amplification plots for 1.5-fold dilutions of a KAZ plasmid amplified with Applied Biosystems PE2 TaqMan. Assay under Fast run conditions using TaqMan. Fast Advanced Master Mix. Quantities assayed, and Ct (SD): 1,000 copies, 27.9 (0.063); 1,500 copies, 27.4 (0.059); 3,000 copies, 26.4 (0.060); 4,500 copies, 25.8 (0.047); 6,667 copies, 25.2 (0.049); 10,000 copies, 24.5 (0.041). NTC = no-template control. (B) Standard curve generated from the Ct values.

Excellent reproducibility and 10-log dynamic range

Figure 6

Figure 2. Real-time PCR reproducibility. This plot shows results from amplification of KAZ target plasmid DNA in 10-fold dilutions using the 96-well block. The data show highly reproducible results over 10 logs of input template amount, illustrating the broad linear dynamic range of the system.


The QuantStudio 3 system also supports probe-based assays and intercalating dyes. TaqMan probe-based assays enable outstanding specificity and sensitivity. Applied Biosystems SYBR Green chemistry is an economical alternative for target identification or initial screening assays. The QuantStudio 3 system has four filters calibrated for FAM/SYBR Green, VIC, ABY/NED/TAMRA, and JUN/ROX dyes. 

Melt curve analysis

Figure 3. Melt curve analysis using the online version of the software. In this experiment, 96 replicates of human genomic DNA were amplified using Applied Biosystems SYBR Select Master Mix with primers for RNase P followed by a dissociation step. The reactions were run under Fast run conditions, showing Ct uniformity with a mean of 25.7 (SD 0.077), and thermal uniformity as measured by the derivative peak with a melting temperature (Tm) of 84.17°C (SD 0.07°C).

Genotyping analysis

SNP Genotyping Assay C_29086771_20, with both PCR and allelic discrimination performed on the QuantStudio 5 Real-Time PCR System. The novel use of real-time PCR data to plot SNP cluster progress aids in calling ambiguous samples and reduces run times by displaying the optimal number of cycles necessary for maximum cluster separation.
