MagAttract DNA Blood Mini M48 Kit
For automated purification of genomic DNA from 100–200 µl blood samples
- Rapid purification of up to 6 µg high-quality DNA
- Flexible purification of 6–48 samples per run
- Easy optimization of DNA concentration
The MagAttract DNA Blood Mini M48 Kit provides automated purification of genomic DNA on the BioRobot M48 using proven MagAttract magnetic particle technology. DNA purification and magnetic separation take place in the pipet tips, increasing the efficiency of the procedure. Up to 48 samples can be processed per run in increments of 6 samples. Variable elution volumes enable easy optimization of DNA concentration.
The MagAttract DNA Blood Mini M48 Kit is designed for fully automated DNA purification. Proven MagAttract magnetic particle technology in combination with the BioRobot M48 workstation provides high-quality DNA, suitable for direct use in sensitive downstream applications. Advantages of the system include scalable sample volumes and elution volumes (see table ), giving the yield and concentration of high-quality DNA appropriate for the intended downstream application.
|Sample||Kit||Protocol||Amount of starting material (µl)||Elution volume (µl)|

MagAttract technology combines the speed and efficiency of silica-based DNA purification with the convenient handling of magnetic particles. Optimized buffers lyse samples, and DNA binds to the silica surface of the magnetic particles in the presence of a chaotropic salt (see flowchart " MagAttract DNA Blood Mini M48 procedure"). DNA bound to the magnetic particles is then efficiently washed. Two different wash buffers are used, followed by a rapid rinse with distilled water, which considerably improves the purity of the DNA. High-quality DNA is eluted in the water provided.
DNA purified using the MagAttract DNA Blood Mini M48 Kit can be used in a wide range of downstream applications, including:
|applications||PCR, qPCR, real-time, genotyping, sequencing|
|format||Sample tube (1.5 ml, 2 ml)|
|mainsampletype||Whole blood, buffy coat|
|forautomatedprocessing||BioRobot M48 Workstation|
|timeperrunorperprep||23 minutes – 2.5 hours|
We recommend to process a minimum of 24 samples per run on the BioRobot M48 workstation. While the software will allow as few as 6 samples to be run at a time, small amounts of buffer do remain at the bottom of the reagent trays after each run. This may lead to reagent shortage, unless the remaining buffers are being reused.
DNA isolated from 200 µl blood using the MagAttract DNA Blood protocol and DNA isolated from 10 µl blood using the MagAttract DNA Forensic Trace protocol was shown by PCR after 3 and 4 years, respectively to still be stable.
