Product Information
| Name | 20nm Colloidal Gold, Ultra-high Concentration |
| Dimension | 20nm |
| Concentration | 100±5OD |
| Storage | store at 2-8℃，1 year |
| Instruction | Storage: This product can be shipped at room temperature. After receiving, it is recommended to store at 4℃~8℃, avoid placing it at the air outlet and inner wall of the refrigerator, and it is strictly forbidden to freeze it. The delamination caused by long-term placement and the gold spots caused by the evaporation of water on the inner wall of the bottle are normal phenomena and generally do not affect the use. When taking or dispensing, please use a clean container to avoid contamination and colloidal gold accumulation, and it is recommended to use PC transparent material. Use within 2 months after opening. BND or NaN3 preservatives are recommended for buffers used in the colloidal gold labeling process and ProClin series is avoided. The pH of colloidal gold solutions may change after long-term storage, and it is recommended to re-optimize labeling conditions before use. If the adhesion, accumulation, dead gold or colloidal gold is not normal due to improper storage or use, you shall be responsible for it. The product is used after passing the inspection. If the product is used directly without product inspection, it will be responsible for the adverse consequences. |

Colloidal gold is a particle made of chloroauric acid under the action of a reducing agent, due to the negative charge on the surface, it can interact with the positive charge on the surface of proteins and other molecules, so that the proteins and the like are firmly bound to the surface of colloidal gold. Therefore, colloidal gold is widely used in immunodiagnostic products as a tracer. The colloidal gold prepared by the traditional method has poor homogeneity, and the concentration is (0.01%-0.04%). This product adopts an innovative method, and the colloidal gold prepared by this product has good uniformity, monodispersion (particle size CV<8%), high concentration (1%), and has the characteristics of high labeling efficiency, saving marking raw materials and energy consumption, and easy operation. Our company can provide 20nm, 30nm, 40nm, 50nm, 60nm, 70nm, 80nm ultra-high concentration colloidal gold products, if you need other particle sizes, you can contact the company for customization.
Benefits:
The particle size is strictly controlled and monodispersed.
The unique high-concentration labeling process can reduce the cost of labeled antibodies (or antigens) by up to 80%.
Simplify the marking process and reduce production and centrifugation equipment costs.
Remark：These protocols are for reference only. Solarbio does not independently validate these methods.
