MACHEREY-NAGEL purification products contribute to the fight against SARS-CoV-2 pandemic.


Facing the current COVID19 outbreak molecular testing laboratories rely on workflows to isolate SARS-CoV-2 RNA from respiratory samples.
Multiple labs have included MACHEREY-NAGEL´s NucleoSpin and NucleoMag kits for isolation of viral RNA into their workflows, among them the two WHO reference laboratories, the Institute Pasteur Paris (France) and the National Institute of Health (Thailand).


We are supporting all labs by providing guidelines for sample preparation and nucleic acid extraction with MN kits in compliance with WHO and CDC recommendations. The recommendations include all our NucleoSpin and NucleoMag kits suitable for extraction of viral RNA.


MN protocol recommendations for respiratory samples (swabs, sputum, bronchoalveolar lavage).

Nucleomag DNA/RNA Water

Monitoring coronavirus in sewage could help to estimate the total number of infections. Infectious diseases that are excreted in urine or faeces, such as SARS-CoV-2, can be tracked by analyzing wastewater. Worldwide many researchers started to use wastewater testing to be able to early on identify a potential reoccurrence of the virus in certain communities. Routine wastewater surveillance might be an efficient, non-invasive tool to detect new COVID-19 infections and might help to limit the health and economic damaged caused by COVID-19.


To support our customers with this new approach we summarized the most common methods used for sample concentration, including filter- and non filter based methods. Because of their superior PCR inhibitor removal we recommend to either use NucleoMag® DNA/RNA Water.
