Diagnostic method for serological testing of Covid-19 antibodies

Application Note #169

Schematic representation of Covid-19 diagnostic method: SARS-CoV-2 specific antibodies from human serum are detected on MP-SPR sensor functionalized with virus proteins.

Considering the indisputable need for Covid-19 related diagnostic tools, we have developed a dedicated serological testing method based on MP-SPR technology. The combination of MP-SPR instrument and optimized sensor format functionalized with virus proteins enabled rapid detection of SARS-CoV-2 antigen-specific antibodies in human serum. The measurement accuracy has been proven with seropositive patient samples and validated with certified reference serum materials. As alternative to currently existing methods, BioNavis will launch a Covid-19 diagnostic kit to be used for immunity surveys across populations and screening the efficacy of treatments developed against SARS-CoV-2.
