" ... The DETECTR method is unique in that it is simple. Patients provide a sample in the form of a nasal or oral swab, the RNA is converted to DNA via a reaction combined with an initial isothermal amplification and then CAS12 is mixed with pre-defined SARS-COV-2 guide sequences with the reaction read out on Mammoth’s lateral flow strips. The CAS12 protein searches across the DNA sample to look for the presence of the programmed SARS-COV-2 sequence. If there is a match, CAS12 binds to the DNA and gives off a signal by cleaving reporter molecules, causing the strip to change color. ... "
