1. Wide detection range

Colloidal gold immunochromatography (GICA) can be used to detect both antigens and antibodies. It is widely used in the diagnosis of animal diseases and detection of veterinary drug residues.

2. Easy operation

It has the characteristics of simple operation steps, no instrument required, no sample processing, and direct visual interpretation of detection results, which does not require technical skills for operators.

" Generally, it only takes 5-10 minutes to obtain the test results. Compared to other methods, such as ELISA, which takes 1-2 hours and PCR, which takes 3-4 hours, the detection time is shortened, which is currently not achievable by other detection methods.

4. Sensitivity

Using & Nbsp; The lower limit of diagnostic analysis for monoclonal antibodies can reach 10pg. By utilizing the principle that gold particles can catalyze the reduction of silver ions to metallic silver, a silver developer is used to enhance the visibility of gold particles, improving the sensitivity of the determination, which can exceed the sensitivity level of ELISA

Due to the physical binding process of colloidal gold labeled proteins, which are firmly bound and rarely cause changes in protein activity, the reagent is very stable and not affected by external factors such as temperature. It can be carried around and tested at any time, and the test results can also be stored for a long time
