ABI PRISM® 3130xl Genetic Analyzer Product Introduction

The ABI PRISM® 3130xl Genetic Analyzer is a high-performance capillary electrophoresis-based genetic analysis platform developed by Applied Biosystems (now part of Thermo Fisher Scientific). It is widely used in molecular biology, genomics research, clinical research, pharmaceutical development, forensic science, and academic laboratories for Sanger DNA sequencing, fragment analysis, mutation detection, SNP analysis, and microsatellite analysis.

The ABI PRISM® 3130xl Genetic Analyzer utilizes advanced 16-capillary electrophoresis technology to provide high-throughput DNA analysis with excellent accuracy and reproducibility. Compared with traditional single-capillary systems, the 16-capillary design significantly improves sample processing efficiency, allowing researchers to analyze multiple samples simultaneously while maintaining high-quality sequencing results.

The instrument integrates laser-induced fluorescence (LIF) detection technology with multi-color fluorescent dye chemistry. It can detect fluorescently labeled DNA fragments generated through sequencing reactions or fragment analysis workflows. The system is fully compatible with BigDye™ Terminator sequencing chemistry, making it suitable for high-quality Sanger sequencing applications, including PCR product confirmation, plasmid verification, gene cloning analysis, and mutation validation.

One of the key advantages of the ABI PRISM® 3130xl Genetic Analyzer is its automated operation capability. The system features an Automated Polymer Delivery System (APDS), which automatically delivers and replaces separation polymers, reducing manual intervention and improving laboratory productivity. The instrument supports 96-well and 384-well microplate formats, enabling efficient batch processing for research laboratories with medium-throughput sequencing requirements.

For fragment analysis applications, the ABI 3130xl provides reliable sizing accuracy and excellent resolution. It is commonly used for STR profiling, microsatellite instability testing, SNP genotyping, linkage analysis, and DNA fingerprinting. Combined with software solutions such as GeneMapper® Software, the system provides powerful data analysis capabilities for accurate allele calling and fragment sizing.

Although newer next-generation sequencing platforms have become increasingly popular, the ABI PRISM® 3130xl Genetic Analyzer remains valuable in many laboratories due to its stability, mature technology, and relatively low operating cost. Refurbished ABI 3130xl systems are particularly attractive for universities, research institutes, biotechnology companies, and testing laboratories that require dependable Sanger sequencing and fragment analysis capabilities without the investment required for new instruments.

When purchasing a used or refurbished ABI PRISM® 3130xl Genetic Analyzer, users should evaluate key components including the capillary array condition, laser detection performance, spectral calibration results, software compatibility, polymer delivery system, and maintenance history to ensure reliable long-term operation.
