Enzyme-Linked Immunosorbent Assay

Enzyme-Linked Immunosorbent Assay

In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.

Coronavirus

Coronavirus

Coronaviruses, including the severe acute respiratory syndrome coronavirus (SARS-CoV), are enveloped viruses characterized by their single-stranded, positive-sense RNA genome and helical nucleocapsid structure. The hallmark of these viruses is their club-shaped spike (S) glycoproteins that protrude from the viral envelope, facilitating attachment to host cells. Typically, coronaviruses infect the upper respiratory tract, often causing mild or asymptomatic disease. However, certain strains like...

Area of Science:

Virology and Molecular Diagnostics
Public Health and Epidemiology
Bioinformatics and Data Science

Background:

The COVID-19 pandemic necessitates efficient and effective SARS-CoV-2 testing.
Existing US Food and Drug Administration (FDA) Emergency Use Authorization (EUA) data for RT-qPCR tests are fragmented and difficult to compare.
Variations in RT-qPCR protocols, target genes, and reporting standards hinder test replication and quality assessment.

Approach:

Developed EUAdb (EUAdb.org), a centralized, relational database for EUA-issued SARS-CoV-2 RT-qPCR diagnostic tests.
Implemented a standardized ontology to curate and organize test information, including reagents, controls, target genes, and limit of detection.
Focused on addressing data standardization, completeness, and accessibility issues present in existing FDA resources.

Key Points:

EUAdb provides standardized, curated data on molecular diagnostic tests for SARS-CoV-2.
The database facilitates comparison and replication of RT-qPCR tests by addressing data fragmentation and lack of standardization.
Addresses limitations in publicly available EUA data, including missing test information and non-standardized formats.

Conclusions:

EUAdb aims to enhance the comparability and reproducibility of SARS-CoV-2 testing nationwide.
The database supports consistent, universal, and high-quality diagnostic testing for COVID-19.
