MagSi-NA Pathogens Kit

Magnetic-bead based total nucleic acid extraction for pathogen detection (suited for Covid-19)

The MagSi-NA Pathogens Kit enables easy extraction of DNA and RNA from serum, plasma, oropharyngeal swab/nasopharyngeal swab, and any other respiratory samples for pathogen detection. Due to the kit’s simple protocol and ready-to-use agents, it is easy to scale to small, medium, and high-throughput automation, as well as using small elution samples. The MagSi-NA Pathogens Kit utilizes magnetic beads to ensure a consistently high yield of DNA and RNA and is suitable for use with various enzymatic downstream applications, including qPCR and qRT-PCR isothermal amplification.

Additional MagSi Pathogens Kits Available

Up to 6 times 96 samples are added to the wells of up to 6 deepwell plates. First, all samples are lysed under denaturing conditions by addition of lysis buffer including proteinase K and Poly-A-RNA. Magnetic MSP beads and binding buffer are then added to every sample

During the isolation procedure the magnetic MSP beads will bind the nucleic acids from all (up to 6) samples by transferring them in a serial manner to the next sample plate, until all (up to 6) samples have been incubated with magnetic MSP beads. 

After this, the magnetic MSP beads are washed in 3 deepwell plates containing alcoholic buffers. Finally, the nucleic acids are collected from the sample plates and released into an elution plate using a low-salt elution buffer.  

They can then be directly used for downstream applications

Ct Comparison With and Without MSP

Fig.1 Four concentrations of MS2 RNA were spiked at different positions in sample plates 1, 4 and 6 and used for the extraction protocol. qPCR results generated with the eluted RNA samples demonstrate  that there is no significant difference in RNA recovery between the binding steps of MagSi-NA Pathogens MSP, and compared to the standard MagSi-NA Pathogens procedures without pooling.

Fig 2. Ct values obtained by RT-qPCR from a COVID-19 positive saliva sample after RNA extraction without pooling and with MSP. The same sample was added to the first and last sample plates to evaluate sensitivity. No difference could be determined.
