2. Realizing semi quantitative or quantitative detection

Currently, there are three types of quantitative detection using immune colloidal gold technology: the first is to visually compare the color of the test strip to divide the results into negative, weak positive, medium positive, and strong positive; the second is to design the reagent of the detection line to only bind a known amount of analyte, and any excess analyte will bind to the next detection line.

Generate a thermometer style strip gradient; The third method is to use a reflective densitometer to measure the color intensity of color bands or spots, and convert the color intensity into a digital indicator. The first two detection methods, although simple, can only provide semi quantitative results; Although the third detection method can achieve quantitative detection, it requires instruments and is inconvenient to operate. The implementation of new, simple and practical quantitative detection techniques will enable immunocolloidal gold technology to be applied in veterinary testing& Nbsp; For a wide range of applications
