Immunocolloidal gold diagnostic technology& Nbsp; Initially used in the detection of chorionic gonadotropins in urine and serum, with the continuous development of technology in China, some experts and scholars have proposed that colloidal gold can be used as a substitute enzyme for markers, participating in filtration experiments, and widely used in the production of human immunodeficiency virus antibody detection kits. The gold standard immunocolloidal gold diagnostic technology has the characteristics of easy operation and is widely used in infectious disease pathogen antibodies and pregnancy tests. However, its application in veterinary diagnosis is still in its early stages

Gold Label Card

Immunocolloidal gold diagnostic technology is widely used in the labeling of monoclonal antibodies, and therefore has good specificity.

3. Good Sensitivity Immunocolloidal gold diagnostic technology has good sensitivity and is not affected by its specificity. In some experimental operations, the sensitivity is at 1ng/ml or slightly lower, and the sensitivity of a few experiments is not within this range. The use of immune gold and silver staining and biotin affinity system can improve the sensitivity of silver enhancement tests.

4. The difficulty of judgment is low. Due to the obvious color of the test, negative and positive can be judged by the naked eye.

5. Gold staining method and biotin affinity system can improve the sensitivity of silver enhancement tests.

The immunocolloidal gold diagnostic technology of the standard card can display the test results within 5-10 minutes, which is significantly shorter than other methods
