The colloidal gold immune technology of the Antigen test utilizes the high electron density of gold particles and uses colloidal gold as a tracer marker for immunoassays. Colloidal gold labeling is essentially the coating process of adsorbing proteins and other macromolecules on the surface of colloidal gold particles. Colloidal gold immunological techniques include immuno-colloidal gold light microscopy staining, immuno-colloidal gold electron microscopy staining, spot immunogold percolation method, and colloidal gold immunochromatography. So what is the colloidal gold immune technology and the prospect of an Antigen test? Let's take a look at it next.
The preparation of a colloidal gold solution for the Antigen test adopts the trisodium citrate reduction method to prepare a colloidal gold solution. Take 1000 mL of ultrapure water and heat it to boiling on a magnetic stirrer, add 40 mL of 1% chloroauric acid solution, when the solution boils again, quickly add 36 mL of 1% trisodium citrate solution, continue to boil when the color of the solution turns purple 5min, turn off the heater, and restore to the original volume with ultrapure water after cooling. The average diameter and Zeta potential of colloidal gold particles were measured with a nanoparticle size analyzer and stored at room temperature in the dark. So what is the information about the preparation of colloidal gold solutions for the Antigen test? Let's take a look.
After the new coronavirus invades the human body, the protein carried by the virus itself has antigenic activity, which will stimulate the antibodies produced by human immune cells to resist the virus, firstly antibody immunoglobulin M (IgM), then antibody immunoglobulin G (IgG). Immunoassay technology can detect whether there are proteins (antigens) carried by viruses and antibodies produced due to virus invasion in the human body.
Recently, Bioteke Sterile Disposable Virus Sampling Kit has passed the US FDA 510K registration with its excellent preservation performance and high virus detection sensitivity. After obtaining the EU CE certification, UK MHRA registration, Canada MDEL, Brazil certification, Saudi Arabia certificati
