COVID-19 Resources and Measures

To combat the rapidly evolving COVID-19 pandemic, INFRAFRONTIER is offering several resources, related strains and emergency archiving services to the global research community with the aim to aid COVID-19 research and minimise the loss of valuable mouse strains during the crisis.

COVID-19 Resources ofeered by INFRAFRONTIER Partners


The coronavirus (COVID-19) pandemic is not only a serious threat to global public health, it also deeply affects the social and economic life worldwide. INFRAFRONTIER, the European Research Infrastructure for the generation, phenotyping, archiving and distribution of model mammalian genomes, is fully committed to support researchers around the globe to develop a vaccine against SARS-CoV-2 and to find treatments for COVID-19.

COVID-19 related EMMA strains


The following EMMA strains are related to SARS-CoV-2 infection via their human orthologues. The table below contains EMMA strains that could be used for COVID-19 research.

EM:05839 / CNR, Marcello Raspa: / frozen germplasm

Reference A SARS-CoV-2-Human Protein-Protein Interaction Map Reveals Drug Targets and Potential Drug-Repurposing

'the Spike protein (S) interacts with the GOLGA7-ZDHHC5 acyl-transferase complex, which likely mediates palmitoylation on its cytosolic tail'



EMMA Strain Details

EM:05697 / HMGU, Susan Marschall: / frozen germplasm 

EM:10456 / ICS, Mohammed Selloum: / frozen germplasm 

Reference A SARS-CoV-2-Human Protein-Protein Interaction Map Reveals Drug Targets and Potential Drug-Repurposing


'We also identified an interaction of Nsp5 (C145A) with tRNA methyltransferase 1 (TRMT1), which is responsible for synthesis of the dimethylguanosine (m2,2G) base modification on both nuclear and mitochondrial tRNAs40. We predict TRMT1 is also cleaved by Nsp5, removing its zinc finger and nuclear localization signal and likely resulting in an exclusively mitochondrial localization'

Emergency Archiving During COVID-19 Crisis


Due to the current coronavirus  (COVID-19) situation, there is need to archive various valuable mouse models. Traffic restrictions and other severe measures to slow the spread of the pandemic are in force, but some EMMA nodes are still active and may archive valuable strains.

Please directly contact your closest EMMA node from the list below for archiving possibilities. In contrast to the standard EMMA archiving service, which includes evaluation by an external scientific committee and is free of charge for depositors, the emergency service may come with service charges. Details will be provided by the EMMA nodes.

As the situation in the different countries is changing constantly, we can not give any guarantees. Whether mice can be imported also strongly depends on whether carrier companies are still servicing the respective route from the depositor institute to the EMMA node.
