Rapid Antigen Detection Kit Nasal (Colloidal Gold​)

Product specifications

Theory

The SARS-CoV-2 Antigen Test Kit (GICA) is a colloidal gold enhanced double antibody sandwich immunoassay for the qualitative determination of nucleocapsid (N) protein of SARS-CoV-2 virus in human nasal (anterior) swab.

SARS-CoV-2 antibody is immobilized in the test region on nitrocellulose membrane. If the specimen contains SARS-CoV-2 antigen, during the assay specimen is allowed to react with the colored conjugate (SARS-CoV-2 antibody-colloidal gold conjugate); the mixture then migrates chromatographically on the membrane by the capillary action. An SARS-CoV-2 positive specimen produces a distinct color band in the test region, formed by the specific antibody antigen colored conjugate complex "(Au-SARS-CoV-2-Ab)-(SARS-CoV-2-Ag)- (SARS-CoV-2-Ab)". Absence of this colored band in the test region suggests a negative result. A colored band always appears in the control region serving as procedural control regardless of the specimen contains SARS-CoV-2 or not.
