Continuous micro-magnetic immunodetection system

Abstract

The invention discloses a continuous micro-magnetic immunodetection system which comprises a support (1) and a crawler-type conveyor belt (2) made of a flexible material, a driving wheel (3) and a driven wheel (4) which are used for driving the crawler-type conveyor belt (2) to circularly convey are arranged on the support (1), and at least one row of reaction cup clamping seats (2.1) which are distributed at equal intervals are arranged on the crawler-type conveyor belt (2) in the conveying direction of the crawler-type conveyor belt (2); the reaction cup clamping seat (2.1) is provided with an overflow port facing the edge of the crawler-type conveyor belt (2); a thermostatic chamber (5) is arranged on the support (1), and the crawler-type conveying belt (2) is partially or completely located in the thermostatic chamber (5). The design of the system is simplified, the cost of the system is reduced, the detection steps can be simplified, and the detection time can be shortened.

Description

technical field [0001] The invention relates to the technical field of biological detection systems, in particular to a continuous micro-magnetic immune detection system. Background technique [0002] Existing immunoassays include enzyme-linked immunoassay, magnetoenzyme immunoassay, immunoturbidimetric assay, chemiluminescence immunoassay, radioimmunoassay and other methods. Enzyme-linked immunoassay is difficult to adapt to high-sensitivity assays due to its low sensitivity. Although the detection sensitivity is improved, the cost performance is lower than that of chemiluminescence immunoassays with similar detection methods. Radioimmunoassays are rarely used because of radioactive contamination. Although immunoturbidimetry is simple, it is limited by the turbidimetric methodology and has low reliability and low sensitivity, so it is only suitable for occasions with low requirements. SUMMARY OF THE INVENTION [0003] The present invention aims to at least partially over...

Problems solved by technology

[0002] Existing immunoassays include enzyme-linked immunoassay, magnetic enzyme immunoassay, immunoturbidimetric assay, chemiluminescence immunoassay, radioimmunoassay and other methods. ELISA has been difficult to adapt to high-sensitivity detection because of its low sensitivity. Magnetic enzyme immunoassay Although the detection sensitivity has been improved, the cost performance is lower than that of chemiluminescent immunoassays with similar detection methods. Radioimmunoassays are rarely used because of radioactive contamination.

Although the immunoturbidimetry is simple, but limited by the turbidimetric methodology, the reliability is relatively low, and the sensitivity is not high, so it is only suitable for occasions with low requirements.
