The MagNA Pure Compact Instrument is an optimal solution for fast and easy automation of nucleic acid purification from small sample numbers. It performs 1 to 8 nucleic acid purifications from a broad variety of sample materials (e.g., mammalian blood, serum, plasma, or cells) in 20 to 45 minutes (depending on the protocol). The system is highly flexible concerning the sample and elution volumes needed to obtain the necessary nucleic acid concentration for each application. The samples are tracked, and clots, tip-loss, cartridges, and volumes are detected and checked during the processing run. All information is saved for documentation purposes.
The high-quality nucleic acids isolated with the MagNA Pure Compact System are suitable for a broad range of applications in nucleic acid research, including:
- Gene expression analysis using PCR and RT-PCR on the LightCycler® System (see Figures 5 and 6) or on standard block cyclers.
- Microarray analysis

Figure 2: Sensitivity of DNA Isolation. Citrated plasma was spiked with a dilution series of human Parvovirus B19 in the range of 102 to 107 copies per milliliter of plasma. Nucleic acids were isolated from 200 µl of spiked plasma using the MagNA Pure Compact Instrument and the MagNA Pure Compact Nucleic Acid Isolation Kit I. Elution was done in 100 µl, of which 5 µl were used for a LightCycler® PCR. As little as 100 copies/ml (= 1 copy per PCR) are detected, showing excellent sensitivity and linearity.

Figure 3: Scalability of DNA yield. Different amounts of K-562 tissue culture cells were used to isolate DNA using the MagNA Pure Compact Nucleic Acid Isolation Kit I. In the range from 1 x 105 to 1 x 106 cells, DNA yield (determined by OD measurement) perfectly matches the number of cells that were processed by the MagNA Pure Compact Instrument.

To demonstrate the robustness of the elution process when choosing different sample and elution volumes, a 1.2 kb collagen fragment was amplified in a block cycler.

Figure 5: LightCycler® System PCR detection of different human targets in research samples. DNA eluates from whole blood samples were generated with the MagNA Pure Compact System, split immediately after elution, and stored at different conditions. LightCycler® PCR was performed, using two parameters which detect internal sequences (Factor V and Her2neu) and two parameters which detect spiked sequences using the internal control function of the MagNA Pure Compact Instrument (Epstein-Barr Virus and Parvovirus B19). No significant influence of different storage conditions on amplification performance was observed. LightCycler® Crossing Point: Crossing Point as determined by LightCycler® System PCR.
Figure 6: LightCycler® System PCR detection of Her2neu sequences in MagNA Pure Compact eluates. DNA was isolated from human whole blood research samples stabilized with different anticoagulants. The endogenous sequence Her2neu was detected by LightCycler® PCR. Additionally, the eluate stability at different conditions was demonstrated. No significant deviation in LightCycler® Crossing points is observed using either anticoagulants or different storage conditions.

The MagNA Pure Compact Instrument utilizes a proven magnetic-bead technology for the isolation process. This technology has been successfully used throughout the world to generate research success and numerous publications over the last ten years. The choice of nucleic acid purification protocol depends on the sample type and the specific application. The MagNA Pure Compact Instrument incorporates a variety of experimental protocols using different specimen amounts (100 - 1,000 µl) and elution volumes (50 - 200 µl) from a wide variety of sample materials (blood, blood cells, serum, plasma, tissue, or cultured cells).

The MagNA Pure Compact Instrument is designed with a variety of intelligent features to eliminate cross-contamination and to assure maximum safety throughout the purification workflow.
- Quickly and easily track samples and reagents with the integrated barcode scanner and pre-labeled reagent cartridges and elution tubes.
- Protect each sample from cross-contamination with the instruments synchronized stage movement, integrated HEPA filter, UV decontamination, and pre-filled and sealed reagents and disposables.
- Ensure isolation success throughout the purification with the instruments sensor for tip- loss, clot, and cartridge detection.
- Isolation protocols for blood and plasma automate pipetting of an internal control during the isolation process directly into the lysis buffer, to avoid its degradation by extracellular nucleases present in these specimens.
MagNA Pure Compact Isolation Kits
All isolation kits contain optimized reagents that are prefilled in sealed cartridges, eliminating reagent mix-up or contamination. The supplied Piercing Tool penetrates the cartridge seals during the purification protocol. The Reaction Tips and the Piercing Tool are delivered in Tip Trays that can be easily placed into the instrument. Easy-to-follow software guides the user through the setup of the instrument. This software runs on an integrated personal computer operated by a touchscreen monitor and a barcode reader to facilitate data entry and documentation. The barcode on the Reagent Cartridge contains the information regarding the isolation kit used (e.g., kit name, expiration date). Entering this barcode leads to a preselection of protocols for the corresponding isolation kit and the selected sample and elution volumes. Run documentation can be saved, printed out with an external printer, or routed via host connectivity.
- Integrated computer with touchscreen monitor.
- Easy navigation/guidance throughout setup and run.
- Select pre-installed protocols by scanning the barcode of the Reagent Cartridge.
- Time-saving state-of-the-art user management.
- Simpler data management through host connectivity.
