The test is an antigen-capture immunochromatographic assay, which detects the presence of Strep A in throat swab samples. Monoclonal antibodies specifically against Strep A are 1) conjugated with colloidal gold and deposited on the conjugate pad and 2) immobilized on the test line of the nitrocellulose membrane. When adequate volumes of the test sample is added the antibody conjugate is rehydrated and the Strep A, if any in the samples, will interact with the colloidal gold conjugated antibodies. The antigen-antibody-gold complex will migrate towards the test window until the Test Zone (T) where they will be captured by immobilized antibodies, forming a visible pink line (Test band), indicating a positive result. If Strep A are absent in the sample, no pink line will appear in the Test Zone (T), indicating a negative result.
Strep A Test Kit
The Strep A Antigen Test is an advanced antigen-capture immunochromatographic assay designed for the rapid and accurate detection of Strep A in throat swab samples.
Our Strep A Antigen Test offers a swift and reliable solution for detecting the presence of Strep A. This innovative assay utilizes monoclonal antibodies specifically targeting Strep A, which are conjugated with colloidal gold and immobilized on the test line of the nitrocellulose membrane. When an adequate volume of the test sample is added, it initiates the interaction between Strep A and the colloidal gold-conjugated antibodies, resulting in a visible pink line (Test band) in the Test Zone (T) for a positive result. The absence of a pink line in the Test Zone indicates the absence of Strep A in the sample.
