FIELD: biotechnology.
SUBSTANCE: invention relates to biotechnology. A method has been developed for quantifying the content of local antibodies in saliva using the recombinant SARS-CoV-2 S-protein as an antigen.
EFFECT: method showed high efficiency and allows to increase the efficiency of diagnosing coronavirus infection by detecting virus-specific immunoglobulins in saliva.
