<strong>Figure 1 ELISA Validation with SARS-CoV-2 (COVID-19) ORF3b Protein </strong><br>
Antibodies: SARS-CoV-2 (COVID-19) ORF3b Antibody, 9281. A direct ELISA was performed using SARS-CoV-2 ORF3b recombinant protein (10-005) as coating antigen and the anti-SARS-CoV-2 (COVID-19) ORF3b antibody as the capture antibody. Secondary: Goat anti-rabbit IgG HRP conjugate at 1:20000 dilution. Detection range is from 1 ng/mL to 3000 ng/mL

Background:
Coronavirus disease 2019 (COVID-19), formerly known as 2019-nCoV acute respiratory disease, is an infectious disease caused by SARS-CoV-2, a virus closely related to the SARS virus (1). The disease is the cause of the 2019?20 coronavirus outbreak (2). SARS-CoV-2 virus proteins include structural proteins, non-structural proteins and accessory factors. The structure of SARS-CoV-2 consists of the following: a spike protein (S), hemagglutinin-esterease dimer (HE), a membrane glycoprotein (M), an envelope protein (E) a nucleoclapid protein (N) and RNA. SARS-CoV-2 non-structural protein is ORF1ab that consists of 16 proteins (nsp1-nsp16), while accessory factors include ORF3a, ORF3b, ORF6, ORF7a, ORF7b, ORF3b, ORF9b, ORF9c and ORF10. ORF3b may play a role in interferon antiviral system evasion (3).
