Open AccessDevelopment of a new antigen-based microarray platform for screening and detection of human IgG antibodies against SARS-CoV-2
Strategies to contain the current SARS-CoV-2 pandemic rely, beside vaccinations, also on molecular and serological testing. For any kind of assay development, screening for the optimal antigen is essential. He...
