A peptide-based assay discriminates individual antibody response to SARS-CoV-2
摘要
Abstract
SARS-CoV-2 virus is responsible for the current worldwide coronavirus disease 2019 (COVID-19) pandemic
infecting millions of people and causing hundreds of thousands of deaths. Understanding the antibody response to SARS-CoV-2 is crucial for the development of vaccines
therapeutics and public health interventions. However
lack of consistency in methods used to monitor antibody response to SARS-CoV-2 leaves some uncertainty in our fine understanding of the human antibody response mounted following SARS-CoV-2 infection. We developed a peptide-based enzyme-linked immunosorbent assay (ELISA) by selecting 7 synthetic peptides from the spike
membrane
and nucleocapsid protein sequences of SARS-CoV-2
which effectively detects the antibody response mounted by all COVID-19 convalescent tested. Strikingly
the assay shows a profound difference in antibody response among individual subjects
which may have a significant impact on disease severity. Together
our results define an efficient and specific serological assay to consistently measure the antibody response following SARS-CoV-2 infection
as well as help the design of vaccine and therapeuticals for prevention and treatment of COVID-19.
