Applied Biosystems 7500 Real-Time PCR System for Multiplex DNA/RNA Quantification

The Applied Biosystems 7500 Real-Time PCR System is a robust molecular diagnostics instrument integrating precise thermal cycling with advanced fluorescence detection technology. Designed for multiplex quantitative PCR applications, it supports simultaneous detection of up to five targets through a sophisticated five-color multiplexing system, enabled by a CCD camera and halogen lamp excitation source. This system delivers immediate quantitative results without the need for post-PCR processing, making it essential for gene expression analysis, infectious disease testing, and molecular diagnostics workflows.

Key technical features include:

• Integrated real-time PCR thermal cycler and fluorescence detection functionality optimized for DNA/RNA quantification
• Five-color multiplex detection capability allowing high-throughput analysis of multiple genetic targets in a single reaction
• Use of a CCD camera combined with halogen lamp excitation, reducing spectral crosstalk via a multi-component algorithm for enhanced detection accuracy
• Advanced software tools for data analysis, including high-resolution melting curve (HRM) analysis to support genotyping and mutation detection
• Compatibility with TaqMan assays and a range of fluorescence-based chemistries, widely adopted in biotechnology research and clinical molecular diagnostics
• Manufactured in 2005, with a durable design suitable for sustained use in laboratory environments focused on biotechnology, synthetic biology, and bioprocessing applications

Weighing approximately 40.8 kilograms (90 pounds), the system’s compact footprint fits standard laboratory benchtops. Though its software and computer require separate provision, this platform remains a critical tool widely used in molecular biology workflows, particularly those centered on molecular cloning, gene editing validation, and biomanufacturing quality control. The ABI 7500 continues to be valued for its reliability in live-cell genetic quantification and biomedical engineering research contexts where multiplex fluorescence-based PCR quantification is essential.
