Avacta vs Sona18 May 2020 10:10
Quick look at their website. Both companies are partnering GE (Cytiva) and both companies aiming for LFDs. They look slightly ahead in validation.
A LFD comprises a molecule that recognises a very specific antigen (virus). It then binds to a label. Avacta uses affirmers to do the first part whilst Son a look like they are using antibodies from the native american company. Advantage us I think - simpler to produce plus others - see Avacta website. For the label Avacta will probably use colloidal gold but lots of options. Sona have developed these nanorods that enables multiple tests on same stick. They mention sensitivity but in context looks like a lower Limit of Detection.
Logically GE + Sona + Avacta would be a beautiful test, the best test etc etc. Doesnt look like its on the cards yet. One concern is GE looks like the assessor and decision maker.
