Yacoo provide raw materials for test reagents to improve diagnostic efficiency of novel coronavirus pneumonia

 The IgM/IgG antibody detection is significant for the diagnosis of COVID-19, which can shorten the testing time, provide easier and faster operation and make rapid diagnosis of suspected patients and on-site screening of people in close contact. 

The novel coronavirus genes encode multiple structural proteins, such as N protein, E protein, and S protein. These proteins include multiple epitopes. The new coronavirus genes encode multiple structural proteins, such as N protein, E protein, and S protein. These proteins include multiple epitopes. These antigens can be used as immunogens. After the virus infects the human body, it stimulates plasma cells to produce specific antibodies. Using the principle of specific binding of antigens and antibodies, the presence of antibodies can be detected by the antigen, which indirectly proves that the human body has been infected or has been infected with the new corona virus.

Antibody detection reagents are for the detection of blood，including serum, plasma and whole blood. The antibodies detected are divided into two types: IgM and IgG.

Generally, IgM antibodies appear in the early stages of infection, with a short maintenance time and disappear rapidly. IgG antibodies appear in the middle and late stages of infection and can remain in the blood circulation for a long time. A positive blood test can be used as an indicator of infection or previous infection.

At present, there are 12 nucleic acid detection reagents and 8 antibody detection reagents approved by the SFDA. Among them, the antibody detection reagents include 5 colloidal gold methods and 3 magnetic particle chemiluminescence methods.

The novel coronavirus  antibody detection reagent (Colloidal Gold Method) is regarded as auxiliary detection metrics towards on-site screening for suspected cases that have the negative results after nucleic acid testing. This rapid test can aid in the diagnosis of coronavirus infection and significantly shorten the detection time, yielding the results in 15 minutes.
