ACE2, receptor of 2019-nCoV

The novel coronavirus (2019-nCoV) which caused an epidemic of acute respiratory syndrome shares 79.5% sequence identify to SARS-CoV. Recently, several reports indicated that 2019-nCoV and SARS-CoV share the same receptor ACE2 for mediating viral entry into host cells.

ACE2 (angiotensin-converting enzyme-2) is previously known as the receptor for SARS-CoV. Based on structural analysis, Wan et al., and Xu et al., point that ACE2 could be the receptor for 2019-nCoV. Zhou et al., conducted virus infectivity studies and confirmed that ACE2 is required for entry of 2019-nCoV into HeLa cells. More understanding of 2019-nCoV-ACE2 interaction can lead to anti-infective strategies such as ACE2 protein blockade or neutralizing antibodies.

arigo offers IP-grade AEC2 antibody (ARG41099) that is excellent for studying 2019-nCoV-ACE2 interaction and vital infection. Moreover, a series of antibodies and ELISA kit are available to facilitate coronavirus research.

Tools for studying Dengue Virus

Dengue virus
Dengue fever is caused by infection of dengue virus and transmitted by mosquitoes. Dengue virus (DENV) is a single-stranded RNA virus belonging to family Flaviviridae. There are 4 serotypes of the virus (called DEN-1, -2, -3 and -4) have been found. The DENV genome encodes 3 structural (capsid C, membrane M, and envelope E) and 7 nonstructural (NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5) proteins.

Dengue diagnostic testing
Laboratory diagnosis of dengue can be made by detecting viral RNA, NS1 protein, IgM and IgG against DENV. NS1 protein, the early diagnosis marker, can be detected in DENV-infected patients as early as 1 day post onset of symptoms. For primary infection (first dengue or other flavivirus infection), IgM levels are useful for diagnosis of infection by day 3-5 up to over 2–3 months after onset, and IgG levels are elevated after 10-14 days and remain detectable for life. During secondary infection (had dengue or other flavivirus infection in past), IgG levels rise rapidly from 1-2 days after the onset of symptoms. IgM/IgG antibody ratios are commonly used to distinguish primary and secondary infection: primary infection patients have a higher IgM/IgG ratio while IgG levels are typically higher in the secondary infection stage.
