cPass™ SARS-CoV-2 Neutralizing Antibody test for next generation vaccine development and immunity status monitoring

The new Omicron subvariants have caused another global COVID-19 wave due to their remarkable ability to evade immunity. While vaccines and prior infection still prevent severe disease, there is an urgent need to develop new vaccine that can offer better protection against variants, or even universal coronavirus. Neutralizing antibodies (NAbs) are critical human immune defense mechanisms against viral infections as NAbs can bind to sites on the virus and inhibit entry of that virus into the host. Level of NAb has been shown as a good biomarker for adaptive immunity.

In this webinar, Dr. Su Chengxun will introduce the technology behind cPass™, its application in serosurveillance; the difference between NAb and total antibody, and impact of new variants. We will also review cPass™ clinical performance, individual differences in NAb longevity post infection/vaccination, how cPass™ can inform the need for booster, and serve as a powerful tool for next-generation vaccine development.

Speaker Biography:

Chengxun received her PhD training in Biomedical Engineering, Interdisciplinary Graduate School at Nanyang Technological University, Singapore. During her PhD, she focused on developing bio-engineered platforms for disease modeling and drug testing applications, where she applied cutting-edge technologies in cell biology, microfabrication, microfluidics, and molecular biology to develop novel tools to support fundamental and translational research. Using these cutting-edge technologies, Chengxun spearheaded several collaborations with clinicians to investigate immune dysfunction and inflammatory profile in patients who recovered from COVID-19, paving the way for potential intervention strategies.
