COVID-19 SARS-CoV-2 RAST Study

A point-of-care Rapid Antigen Screening Test (RAST) using a lateral flow immunoassay platform with our partner, BioMedomics Inc. The BioMedomics RAST is a lateral flow immunoassay that detects the nucleocapsid protein (NP) antigen of SARS-CoV-2 using a double antibody sandwich assay. The test cassette contains one detection line (T) fixed with anti-SARS-CoV-2 NP antibody and one quality control line (C) fixed with control antibody. When the test sample is treated with lysis buffer and added to the sample well of the test cassette, the fluid will move forward along the test strip via capillary action. If the sample contains NP antigen at levels higher than the limit of detection, the antigen will bind to the NP capture antibody as well as the immobilized detection antibody on the membrane forming a red T line, indicating a positive result. A positive signal at C line provides assurance that the fluid containing the sample material has moved laterally in an appropriate fashion.
