According to an article published in Virus World, RetroVirox has launched a menu of cell-based antiviral services to evaluate experimental therapies and vaccines against coronaviruses, including SARS-CoV-2.

In vitro testing with SARS-CoV-2

Starting today the company will offer in vitro testing with SARS-CoV-2 pseudoviruses to evaluate entry inhibitors against the novel coronavirus causative agent of COVID-19. The assay utilizes pseudoviruses coated with the viral spike (S) protein of SARS-CoV-2 to recapitulate the mode of entry of the novel coronavirus.

Uses of assay

The assay can be used for the following purposes:

  • To determine the neutralizing activity of therapeutic antibodies and antisera
  • To test experimental COVID-19 vaccines using antisera from inoculated animals or humans
  • To evaluate small-molecule and other entry inhibitors targeting the S viral protein, the ACE-2 viral receptor, or host proteases and other targets involved in SARS-CoV-2 viral entry

RetroVirox also performs in vitro assay against several milder forms of seasonal human coronaviruses (hCoV), including the strains OC43, and 229E.
