Description

Technical Field

[0001] The utility model belongs to the field of grain safety detection, and particularly relates to a detection box for rapid on-site screening of mycotoxins. Background Technique

[0002] Mycotoxins widely exist in the links of grain planting, processing, storage and transportation. Most of them have carcinogenic, teratogenic and mutagenic effects, posing a huge threat to the survival and health of human beings. There are probably more than 400 mycotoxins with clear characteristics currently. Among them, the main ones with greater harm and wider pollution range are: aflatoxin, ochratoxin A, deoxynivalenol, zearalenone, T-2 toxin, etc. Therefore, it is necessary to detect mycotoxin contamination in the process of grain receiving, processing, storage and transportation.

[0003] The time-resolved fluorescence microsphere POCT rapid quantitative detection technology uses lanthanide rare earth elements with unique fluorescence characteristics, such as europium (Eu), samarium (Sm) and their chelates, etc. as tracers to label bioactive substances (antigens, antibodies, etc.). After the reaction system (antigen-antibody reaction, biotin-avidin reaction, etc.) occurs, it absorbs ultraviolet light and emits specific fluorescence. By time delay and spectral resolution technology, non-specific interference in the sample is excluded, and the fluorescence intensity in the reaction product is measured with a specific analytical detector. This technology has its unique advantages: (1) High accuracy, and the detection results are in good agreement compared with the instrument confirmation method; (2) Short detection cycle, and the detection time is significantly better than detection methods such as mass spectrometry liquid phase, etc., and the detection work can be directly carried out at the sampling site; (3) High sensitivity, generally a quantitative detection technology 1-3 orders of magnitude higher than ordinary colloidal gold or colored latex immunochromatography methods; (4) Low interference of fluorescence background signal, and the use of an extremely wide stoke shift and an extremely long fluorescence quenching time can distinguish the effective signal from the background fluorescence signal of non-specific reaction, reduce the interference of non-specific fluorescence, and has good specificity, and can be used as an on-site rapid quantitative detection means.

[0004] However, the time-resolved fluorescence microsphere POCT rapid quantitative detection technology requires many tools, such as auxiliary tools such as timers, weighing devices, pipettes, measuring cylinders, etc., as well as homogenizers, vortex mixers, detection incubators, fluorescence detectors, fluorescence quantitative detection cards, consumable tips and instrument centrifuge tube racks. How to safely carry the above tools at one time has become an important problem to be solved in the rapid detection of grain safety. Summary of the Invention
