Immune colloidal gold technique detection tube
Immune colloidal gold technique is a new type of immune labeling technology that uses colloidal gold as a tracer marker to apply to antigens and antibodies. The English abbreviation is: GICT. Colloidal gold is polymerized into gold particles of a specific size by chloroauric acid (HAuCl4) under the action of reducing agents such as white phosphorus, ascorbic acid, sodium citrate, tannic acid, etc., and becomes a stable colloidal state due to electrostatic interaction, called for colloidal gold. Colloidal gold is negatively charged in a weak alkaline environment and can form a firm bond with the positively charged groups of protein molecules. Since this bond is electrostatic, it does not affect the biological characteristics of the protein. In addition to binding to proteins, colloidal gold can also bind to many other biomacromolecules, such as SPA, PHA, ConA, etc. According to some physical properties of colloidal gold, such as high electron density, particle size, shape and color response, coupled with the immune and biological characteristics of the conjugate, colloidal gold is widely used in immunology, histology, pathology and cell fields such as biology. Chromatographic immunocolloidal gold detection reagent is actually an application form formed by combining immunogold labeling technology and antigen-antibody reaction. Compared with ELISA reagents, except for the different markers, it is also subject to the characteristics of antigen-antibody reaction. This detection method has obvious advantages:
*Easy to use, reflected in the simple operation, without special training.
*The test results can be obtained in a short time, and the conclusion can be drawn within 10-15 minutes.
* Good stability in different environments, no refrigeration required.
*In comparison, its production cost and testing cost are both low.
*Various types of test specimens: it can be used for blood, urine or feces, so it is suitable for various examinations.
Based on the above advantages, yanshuitech has developed the detection tube, which allows the sample to be diluted and detected in a closed tube. Thereby reducing the secondary transmission of odor and virus. Eliminate aerosol pollution to the environment. Lateral flow test Tube yanshuitech owns the appearance, utility model and invention patents of this product.
