MAXimum results, minimum effort: MagMAX sample preparation for veterinary diagnostic testing
Sometimes purifying nucleic acid from animal samples can be like trying to pull a needle out of a haystack. Fortunately, the magnetic particle technology of the MagMAX™ sample preparation system helps make purifying nucleic acids from animal samples convenient, flexible, and efficient.
Consisting of MagMAX™ nucleic acid isolation kits along with KingFisher™ or MagMAX™ Express magnetic particle processors, the MagMAX sample preparation system can help handle the difficult challenges faced by veterinary diagnostic labs when extracting nucleic acid from biological fluids and cell-free sample types, such as low processing volumes, low concentrations of extractable nucleic acids, and sample complexity.
The MagMAX sample preparation system is an integrated solution that accelerates, standardizes and automates the extraction of nucleic acids to prepare for downstream molecular analysis. All of this is done without using organic solvents or nucleic acid precipitation, thus minimizing the challenges often encountered with filter-based methods, such as clogging, large elution volumes, and inconsistent yields.
- Fast and easy sample processing—typically less than 30-minute run time for 96 samples
- Process up to 800 samples per day on a single instrument
- Provide higher sensitivity with less sample input
MagMAX achieves equal sensitivity with only 1/10 as much sample as a competitor’s kit. Clinical tracheal and cloacal swab samples were collected from poultry infected with California exotic Newcastle disease (END). RNA was isolated from 50 μL of sample using the MagMAX protocol or 500 μL of samples using the NVSL-validated protocol.
- One system purifies both DNA and RNA from a wide variety of sample types/matrices
- Minimizes hands-on manipulation
- Variety of magnetic particle instruments available for many budgetary, application and throughput needs
Wide variety of sample matrices: linear recovery of synthetic viral RNA from biological fluids. MagMAX™ Lysis Buffer was added to samples of water, plasma, serum and milk, and the lysate was then spiked with a serial dilution of a 466 nt HIV Armored RNA™ transcript. Viral RNA was isolated using the MagMAX™ Viral RNA Isolation Kit. The recovered RNA was analyzed by qRT-PCR.
- Helps minimize the risk of cross-contamination
- Fewer false negatives due to the effective removal of PCR inhibitors
- Helps improve the consistency and quality of nucleic acid extraction yields
Performance of MagMAX kit vs. competitors’ kits. The MagMAX™ Pathogen RNA/DNA Kit outperforms competitor magnetic bead–based nucleic acid purification kits. A high-titer PRRSV-positive serum sample was diluted to create mid-titer and low-titer samples. RNA was purified from each dilution in triplicate following each supplier’s directions and using instrument scripts provided by each supplier. Purified RNA was analyzed by qRT-PCR using PRRSV primers and probes. The lowest Ct values were obtained with RNA purified using the MagMAX™ Pathogen RNA/DNA Kit.
Years of research and development have produced a portfolio of nucleic acid isolation kits optimized to purify RNA and DNA from viruses, selected bacteria and parasites found in sample matrices commonly submitted for veterinary diagnostic testing. Our technology binds RNA and DNA more efficiently than silica membrane methods, offers higher-quality nucleic acid yields, and allows nucleic acids to be eluted in as little as 20 μL (manual extraction) or 25 µL (automated extraction) of nuclease-free water, to deliver more concentrated RNA and DNA.
MagMAX™ Pathogen RNA/DNA Kit—our most versatile solution for veterinary diagnostic labs, providing high-throughput extraction of pathogen RNA or DNA from 50 μL to 300 μL input.
MagMAX™-96 Viral RNA Isolation Kit—offers high-throughput extraction of pathogen RNA or DNA from as little as 50 μL input.
MagMAX™-96 AI/ND Viral RNA Isolation Kit—validated extraction of AIV and NDV RNA for NVSL network labs.
