COVID-19 Epidemic Prevention Exclusive ACE2 & DPP4 Mouse Models Online Reservations Open NOW!
At the end of 2019, an outbreak of the COVID-19 (Coronavirus Disease in 2019) caused by the novel coronavirus, officially named SARS-CoV-2, swept across the world from Wuhan. The World Health Organization’s (WHO) Emergency Committee declared the SARS-CoV-2 outbreak to be a Public Health Emergency of International Concern (PHEIC) on January 30, 2020. Accurate animal models are necessary for verifying the pathogenesis and immune mechanisms of the illness to accelerate research across vaccine development, new drug development, gene therapy, and more. Since the outbreak, the R&D team at Cyagen has made every effort to develop animal models catered to the global SARS-CoV-2 research initiative. As our way of contributing to the international epidemic prevention effort, we are opening service reservations on models for ACE2 and DDP4 receptor targets effective immediately. For consultation and order, please call 86 20-31601779 or email

Why ACE2, DPP4 and APN?
Coronaviruses (CoV) invade human cells mainly through binding with cell membrane receptors; so far, three membrane exopeptidases, DPP4, ACE2, and APN have been identified as entry receptors for human-infecting coronaviruses. Among these, ACE2 is associated with the initial entry and infection of SARS-CoV, while DPP4 is similarly linked with MERS-CoV. At present, APN is only found to relevant to HCoV-229E infectivity, while this coronavirus does not cause severe illness. Although the human coronavirus that combined with APN does not directly lead to lethal disease, with the same high expression level as the receptor of MERS-CoV, it is likely to trigger severe lethal respiratory disease like MERS once infected. Additionally, the spike protein used by coronaviruses to bind to cell surface receptors is susceptible to mutations that alter the target receptors to enter the cell to replicate, which can be seriously life-threatening. Therefore, Cyagen’s expert team of scientists have initiated research and development on animal models for these three main coronavirus receptors, aiming to provide rapid solutions for epidemic prevention research.
