Description
Technical Field
The invention belongs to the technical field of in-vitro diagnosis medical instruments, and particularly relates to a multi-wavelength time-resolved fluorescence immunoassay analyzer.
Background
For more than half a century, the mainstream immunoassay technology is radio immunoassay, enzyme-linked immunoassay, chemiluminescence immunoassay and the like, wherein the radio immunoassay is used in a small amount at present due to the problem of radioactivity, the enzyme-linked immunoassay is gradually replaced due to long detection time, and the chemiluminescence immunoassay is the mainstream immunoassay technology at present. In the field of instant detection such as emergency treatment and the like, chemiluminescence is difficult to widely apply due to complex technology and high cost, and the demands promote instant detection type immunoassay technologies such as colloidal gold immunoassay, fluorescence chromatography immunoassay, colloidal turbidimetric immunoassay and the like. The chemiluminescence immunoassay technology is born in the seventies of the last century, the main technology adopted is magnetic particle chemiluminescence, the core hypothesis is that the separation of specific immune complexes and biological matrixes can be realized certainly through magnetic separation, but in clinical practical application, due to the diversity of clinical specimens, cases of magnetic separation failure cannot be avoided, such as 'jump value' phenomenon caused by nonspecific adsorption due to fibrin adhesion, false positive caused by heterophilic antibodies and the like. Half of the failures are due to magnetic cleaning failures for the instrument itself. Therefore, the cleaning-free immunoassay technology is a research hotspot for nearly two-thirty years, siemens, beckmann and other companies have related technology reserves, a series of high-flux immunoassay systems are provided by Beijing Koimei corporation of domestic enterprises based on the Siemens patent light-activated chemiluminescence technology, and the clinical application of cleaning-free detection is realized for the first time.
The time-resolved fluorescence resonance energy transfer immunoassay (TR-FRET) technology was originally developed by a supramolecular rare earth cryptand ether probe discovered by German Bolames (brahms) company based on Jean-Marie Lehn, Nobel chemical prize-winning France, and overcomes the influence of abnormal alignment accuracy of samples such as hemolysis, hyperlipidemia, jaundice and the like in homogeneous detection. Compared with other immunoassay technologies, the technology has many advantages, does not need a solid phase carrier and a solid phase probe, and has the advantages of good precision and accuracy, simple operation, easy automation and miniaturization and the like.
The core of the time-resolved fluorescence resonance energy transfer method is that two fluorescence molecules are called donor and acceptor respectively, wherein the donor can absorb exciting light and emit fluorescence, and the fluorescence can also be transmitted to the acceptor in a fluorescence resonance energy transfer mode and emitted by the acceptor. Specifically, a chelate label of a rare earth element having a cryptic structure is used as a fluorescence donor, and a short-lived fluorescent molecule having a good spectral overlap with the fluorescence donor is used as a fluorescence acceptor, and Fluorescence Resonance Energy Transfer (FRET) occurs between the donor and the acceptor (second fluorescent label) of the cryptic compound of a rare earth element. In fluorescence resonance energy transfer, the lifetime of the acceptor emitted fluorescence approaches that of the donor. Because the donor fluorescence decay period is long, the donor induces the acceptor to emit fluorescence for a long time, and the fluorescence generated after the acceptor is excited can last for a long time, so that the self-scattered fluorescence with short lifetime can be distinguished through time resolution, and the FRET signal can be easily distinguished from the background of the fluorescence with short lifetime.
The fluorescent donor and acceptor can be covalently linked to different partner molecules, e.g., protein dimers, complementary strands of DNA, antigens and antibodies, ligands and acceptors, and the like. Conventional FRET fluorescent compounds are susceptible to interference from background fluorescence of the sample (serum, plasma, buffers, proteins, chemicals and cell lysates). This background fluorescence has a very short lifetime (on the order of 10-9 seconds) and is easily removed by time-resolved methods. The time-resolved fluorescence resonance energy transfer (TR-FRET) technique combines the FRET technique and the time-resolved fluorescence measurement, and removes the extremely short-lived background fluorescence. After transient photoexcitation, the non-specific short-lived emission drops to zero after a delay of 50-150 microseconds. Whereas TR-FRET fluorophores emit long-lived fluorescence that participates in the FRET process. Thus, long-lived acceptor emission represents the energy transfer upon molecular binding.
