Detection disc applied to full-automatic tubular time resolution detector

Abstract

The invention discloses a detection disc applied to a full-automatic tubular time resolution detector. The detection disc comprises a base, a support bracket, a driving device, a light-shielding base plate, a fixed support disc, a detection connection shell, an upper light-shielding ring, a lower light-shielding ring, a rotary support base and a light-shielding cover plate, wherein the upper light-shielding ring and the lower light-shielding ring are fixed at the upper part of the rotary support base; a plurality of holding cavities which are independent of one other and used for holding reaction vessels are formed between the upper light-shielding ring and the lower light-shielding ring; the light-shielding cover plate is fixed above the upper light-shielding ring; a reaction vessel putting hole, at least one liquid adding hole, at least one extension hole and an excitation light receiving hole are sequentially formed in the same circumference of the light-shielding cover plate; a detection light receiving hole, corresponding to the excitation light receiving hole, is formed in the side wall of the detection connection shell. The detection disc applied to the full-automatic tubular time resolution detector is ingenious in design, simple in structure, low in cost, good in light-shielding property, good in detection repeatability, high in accuracy and capable of achieving full automation, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of time-resolved fluorescence immunoassay, in particular to a detection plate used for a fully automatic tube-type time-resolved detector. Background technique [0002] The time-resolved fluorescence method uses trivalent rare earth ions (lanthanides: europium, bismuth, samarium, etc.) and their chelates as tracers to label antigens, antibodies, nucleic acid probes or biologically active cells. After the complexation of antigens and antibodies, after the synergistic treatment of the enhancer, it produces fluorescence with a long half-life and strong fluorescence, which greatly improves the sensitivity and accuracy of detection. This method has become a standard in modern biomedical research and clinical ultra-trace testing. It is one of the most promising analytical methods and one of the top technologies and methods for ultra-trace analysis. [0003] The detection plate is one of the key devices in the tim...

Problems solved by technology

At present, the structure of the detection plate used in the time-resolved fluorescence analyzer is mostly composed of black coating on the instrument shell, and it is a manual enhancement liquid or luminescent liquid. In addition, the light-blocking property is poor, which is easy to cause interference to the detection signal. At the same time, interference between the detection cups is likely to occur. It has an impact on test results such as repeatability and accuracy of the test
