Avacta has announced the AffiDX® SARS-CoV-2 rapid antigen lateral flow test detects the dominant new variants of the coronavirus, known as the B117, or ‘Kent’, variant, and the D614G variant, as well as the original strain.
The variant, named ‘D614G’, makes a small but effective change in the ‘spike’ glycoprotein that protrudes from the surface of the virus, which it uses to enter and infect human cells.
Research out today in the journal Cell shows that a specific change in the SARS-CoV-2 coronavirus virus genome, previously associated with increased viral transmission and the spread of COVID-19, is more infectious in cell culture.
