Seroprevalence Studies

Surveying the seroprevalence of antibodies to the SARS-CoV-2 virus is key to understanding local infection and exposure rates in specific areas or institutions. Because some people are asymptomatic and may not know they have been infected, population studies are crucial in modeling transmission in the COVID-19 pandemic.
Bio-Plex SARS-CoV-2 Antibody Assays provide flexible options to measure anti-SARS-CoV-2 IgG antibodies in a population. Samples can be assayed to measure any combination of antibodies against SARS-CoV-2 nucleocapsid protein, and spike protein subunits: receptor binding domain, spike, 1, and spike 2.

The Bio-Plex SARS-CoV-2 Antibody Assays are for research use only. Not for use in diagnostic procedures.

Webinars
Role of Aberrant Cytokine Activity in Host Immune Response to COVID-19
In this webinar, we discuss early research and nascent hypotheses regarding the pathophysiology of SARS-CoV-2 induced COVID-19 disease by evaluating cytokine and chemokine profiles, the role of chronic inflammation in comorbidities, and the arc of immune resolution of historical virulent pathogens, such as SARS and MERS.
Multiplex Immunoassays in Vaccine Research and Development
In this presentation, we discuss how multiplex assays are being used on the front lines to understand patient immune response during infection, and discuss the most commonly asked questions around targets, panels, and multi-plate data analysis.
Vaccine Development and Manufacturing
In this talk, we review tips for overcoming developmental hurdles, technologies that can shorten timelines, and novel tools for manufacturing and quality control.
Immunological Response Factors to SARS‑CoV‑2 in Acquired Immunity
In this webinar, we will discuss the immune response to SARS-CoV-2, both in the context of natural exposure to the virus and induced immunity from vaccination. We will also investigate the relationship between symptom severity and the longevity of acquired immunity.
