Problems solved by technology

The radioimmunoassay method can only detect a single index, and it takes 2 to 4 hours to detect a single index, and also requires expensive special equipment such as R-counters, and there are radioactive attenuation and pollution
The detection time of chemiluminescence is short and the sensitivity is high, but it is still an indirect interpretation result of the labeling method. A more objective result interpretation system such as molecular weight has not been introduced, and the detection accuracy is easily affected. The detection of each indicator needs to be specially designed, such as The detection of multiple antibodies has the problems of long detection time and high cost, which is not conducive to the development of grassroots clinical inspection activities

Description

technical field [0001] The invention relates to a high-sensitivity protein chip detection system and an application method thereof, belonging to the technical field of biochips. Background technique [0002] In modern serological detection techniques, in addition to ELISA, radioimmunoassay and chemiluminescence are often used. ELISA method has been widely used in clinical laboratories, especially for the detection of various hepatitis markers. However, due to the complicated operation procedures, the ELISA method takes a long time, and requires expensive laboratory equipment such as microplate readers. The main reason why the ELISA method takes a long time is that the antigen (or antibody) in the liquid phase needs to be diffused to react with the antigen or antibody on the solid phase. Inappropriately shortening the reaction time will reduce the sensitivity below the clinical requirement. Although the one-step rapid detection kit can improve the detection speed, it has th...
