Antigen Corona Test Kit

The coronavirus antigen rapid test kit is a lateral flow assay that qualitatively detects the presence of nucleocapsid (N) protein in upper respiratory samples (nasal swabs). This lateral flow assay is designed with the sandwich immunoassay format. When the specimen is added onto the sample pad of a test cassette, coronavirus N protein binds with colloidal gold-labeled SARS-CoV-2 N protein antibody to form an antibody-antigen (Ab-Ag) complex. The Ab-Ag complex is captured by SARS-CoV-2 N protein antibody (Rabbit monoclonal antibody) when migrating to the test line under capillary action. A red-colored band will appear on the test line, which indicates the specimen is COVID-19 nucleocapsid protein positive. No color band will appear on the test line if the specimen does not contain any coronavirus antigen (N protein), or the antigen level is below detection limit.
 
Coronavirus Antigen (Ag) Rapid Test Kit Principle
The conjugation pad also contains colloidal gold-labeled chicken IgY, which is captured by Goat anti-chicken IgY on the control line as procedural control. A colored band on the control line represents the proper liquid flow through the cassette; the absence of a colored band on the control line indicates insufficient sample or buffer volume.
