Le blog À propos Eppendorf Launches Fullspectrum Qpcr System for Enhanced Detection

For researchers grappling with signal limitations, consumable constraints, and cumbersome protocols in molecular diagnostics, a transformative solution has emerged. The qTOWER iris series of real-time PCR instruments from Eppendorf represents a paradigm shift in fluorescence detection technology, offering unprecedented spectral range, multiplexing capacity, and operational freedom.

Conventional qPCR systems often struggle with signal attenuation and crosstalk, particularly when employing specialized fluorophores or complex multiplex assays. The qTOWER iris series addresses these challenges through its innovative full-spectrum detection capability, spanning from UV-A to near-infrared (NIR) wavelengths. This broad detection range accommodates diverse fluorescent markers—from common FAM and SYBR Green dyes to challenging ROX, Cy5 compounds, and cutting-edge NIR fluorophores—while maintaining exceptional signal-to-noise ratios.

Notably, the system's factory calibration eliminates the need for instrument recalibration when introducing new dyes, significantly streamlining experimental workflows and reducing operational costs.

In an era of increasing multiplex PCR applications, the instrument's 6-plex detection capacity enables simultaneous analysis of six distinct genetic targets or SNP loci within a single run. This advancement proves particularly valuable for gene expression studies, pathogen detection, and genotyping applications, where parallel monitoring of multiple biomarkers enhances research depth and efficiency.

The system's thermal precision (±0.15°C) surpasses industry standards (±0.4°C), ensuring uniform amplification conditions across all reaction wells while minimizing edge effects and nonspecific amplification—critical factors for reproducible, publication-quality results.

Breaking from proprietary consumable models, the qTOWER iris series adopts an open-system architecture compatible with major fluorescent dyes, PCR plates, reagent kits, and assay methodologies. This design philosophy grants researchers complete consumable selection freedom, accommodating both cost-effective generic supplies and specialized premium reagents.

Additional software features include adjustable gain settings for low-intensity signals, facilitating optimization of data quality while reducing method development expenses.

The instrument's human-centric design incorporates intuitive interfaces and near-silent operation (25 dB), creating an optimal research environment. Pre-run diagnostics include comprehensive self-checks and fiber-optic system verification, minimizing operational errors and ensuring consistent performance.

The product line offers multiple configurations:

• qTOWER iris 384 / UV ready: High-throughput 384-well platform with optional UV excitation support
• qTOWER iris touch / UV ready: 10-inch touchscreen interface for standalone operation
• qTOWER iris / UV ready: Standard 96-well format with customizable six-color modules

All models support global voltage standards (100V/115V/230V) and feature specialized modules for protein analysis and thermal shift assays.

Key technological advancements include:

• Linear gradient functionality (0.1°C resolution)
• Comprehensive data accessibility with raw output options
• MIQE-compliant documentation capabilities
• FDA 21 CFR Part 11 compliance modules

The system's versatility extends across environmental monitoring, food safety, pharmaceutical development, and fundamental life science research—from Illumina® sequencing library preparation to complex protein denaturation studies using thermal shift analysis.
