Different concentrations of entire cell lysate were separated on an SDS-page gel and transblotted to a nitrocellulose membrane.
The remedy to the requisition low specificity is to consist of some strips that identify another viral antigen eg Spike protein. This way just if you examine positive for both you take into consideration the result as real favorable. As the evaluation in the post over shows with mass testing you end up with lots of incorrect negatives and false positives and the authorities do not understand what to tell people concerning that. There is a little bit of reality in the anxieties-- yet it is so paternalistic-- as if we were not coping with lots of other fuzzy indications like thermometers. Possibly it just requires to be done initially on smaller scales-- to ensure that people have time to learn how to react.
