Description

Technical Field

[0001] The utility model relates to the field of biotechnology, and specifically is a colloidal gold immunochromatographic test paper card. Background Art

[0002] Colloidal gold immunochromatographic test strip technology is a new in vitro diagnostic technology developed by combining colloidal gold labeling technology, immunochromatographic technology, monoclonal antibody technology and new material technology. This method has now developed into a diagnostic test strip, which is very convenient to use. At present, this technology is also widely used in the detection of pathogenic microorganisms in aquatic animals, such as Aeromonas caviae, Aeromonas sobria, Aeromonas hydrophila, Vibrio harveyi, shrimp yellow head virus (YHV), lymphocystis virus (LCDV) and even tetracycline, chloramphenicol and sulfadiazine.

[0003] There is no drying structure in the traditional colloidal gold immunochromatographic test paper card, so when the external environment is humid, the test paper card is easily wet and moldy. Since there is no shielding on the shell of the traditional colloidal gold immunochromatographic test paper card, the nitrocellulose membrane on the test paper is directly exposed to the outside world, so the nitrocellulose membrane is easily contaminated by the outside world and easily damaged.
