QIAxcel DNA Kits

QIAxcel instruments, when used in conjunction with QIAxcel DNA Kits, provide fully automated size separation and quantification of DNA fragments in up to 96 samples per run. QIAxcel technology, based on capillary electrophoresis using gel cartridges, provides unmatched resolution, speed, and throughput. QIAxcel gel cartridges are reusable, allowing up to 250 runs of 12 samples to be performed. Preinstalled methods suitable for most applications are provided. QIAGEN can also create customized methods for users.

​The QIAxcel DNA Kits are only used in combination with the QIAxcel Advanced System and the QIAxcel DNA Accessories.

Easy high-resolution analysis

QIAxcel instruments use capillary gel electrophoresis to enable fast size-based separation of nucleic acids (see figure " Sample separation process"). Unlike traditional agarose gel electrophoresis, separation is performed in a capillary of a ready-to-use gel cartridge. The samples are automatically loaded into an individual capillary and voltage is applied. The negatively charged nucleic acid molecules migrate through the capillary to the positively charged terminus. As with agarose gel electrophoresis, low-molecular-weight molecules migrate faster than high-molecular-weight molecules. As the molecules migrate through the capillary, they pass a detector which detects and measures the fluorescent signal. A photomultiplier converts the fluorescent signal into electronic data, which are then transferred to the computer for further processing using QIAxcel ScreenGel software. After processing, the data are displayed as an electropherogram or gel image.

QIAxcel DNA Kits simplify separation and analysis of DNA fragments, and provide increased user safety. Just a few simple steps are required: load the gel cartridge, fill and load the buffer tray, load the samples in 96-well plates or in PCR tubes or strips, select the process profile to be used - and go! Tedious gel preparation and extensive user training are eliminated, streamlining the workflow and facilitating integration of the system into the daily lab routine. Within minutes of starting a run, the first results appear in real time on the computer screen (see figure " Reduced run times").

Preprogrammed methods, in combination with the corresponding gel cartridges, allow separation and analysis of a variety of nucleic acids, including single or multiple PCR fragments, DNA digested with restriction endonucleases, and synthesized oligonucleotides.
