LATERAL FLOW DEVICE FOR DETECTION OF NEUTRALIZING ANTIBODIES AGAINST SARS-COV-2

摘要

The present disclosure provides a lateral flow device, and methods of use of the device, for accurately and rapidly detecting a COVID-19 infection in a subject. The lateral flow device described herein detects in a liquid sample from the subject the presence or absence of neutralizing and non-neutralizing anti-S1 spike antibodies as IgM and IgG types. The anti-S1 antibodies neutralizing antibodies (e.g., both IgM and IgG) can block binding between ACE2 antigen and S1 spike protein which is the basis for the design of the lateral flow device.
