Description
Technical Field
The application relates to the field of fluorescent microsphere detection cards, in particular to a fluorescent microsphere test strip and a test paper box.
Background
The time resolution technology based on rare earth nanotechnology is a technology combining Time Resolution Fluorescence Immunoassay (TRFIA) and on-site instant detection (POCT), and is also a non-isotope immunoassay technology. The fluorescence spectrum of a common substance is divided into an excitation spectrum and an emission spectrum, and the fluorescence analysis utilizes the great difference (Stakes) between the fluorescence wavelength of a luminescent substance and the excitation wavelength thereof to overcome the influence of the variegated color in the common ultraviolet-visible light spectrometry. Meanwhile, the photoelectric receptor and the exciting light are not in the same straight line in the fluorescence analysis, and the exciting light can not directly reach the photoelectric receptor, thereby greatly improving the sensitivity of the optical analysis. If the ultra-micro analysis is performed, the stray light of the excitation light will have a serious influence on the result. The best way to address the effects of stray light is to measure without the presence of excitation light. However, the conventional fluorescent marker has a very short light lifetime, and the fluorescence disappears simultaneously with the disappearance of the excitation light. However, some rare earth technologies have long fluorescence lifetimes and still have high residual fluorescence (afterglow) 1-2ms after the excitation is turned off. Therefore, the measurement requirement can be met by capturing the afterglow after the excitation light is turned off, and a time-resolved fluorescence analysis method, that is, an analysis method for measuring the fluorescence intensity after the excitation light is turned off by using a long-acting fluorescent marker, is generated.
TRFIA analysis means that many complexes and proteins in biological fluids and serum can fluoresce themselves. The sensitivity of fluorescence detection using conventional chromophores is severely degraded. Most background fluorescence signals are short lived, and local transient fluorescence interference can be minimized if long half-life labels (e.g., europium) are combined with time-resolved fluorescence techniques. The time-resolved fluorescence immunoassay (TRFIA) is implemented by connecting one end of a chelating agent with a bifunctional group with europium (Eu) and the other end with a free amino group on an antibody/antigen molecule to form an Eu-labeled antibody/antigen, generating an immune complex after immunoreaction, and detecting the fluorescence of the europium (Eu) by time resolution to achieve the purpose of detection. The commonly applied rare earth metals are mainly europium (Eu) and terbium (Tb), the Eu fluorescence has the service life of 1ms and is instable in water, but the instability can be eliminated after the reinforcing agent is added; tb has a fluorescence lifetime of 1.6ms and is stable in water, but has a short fluorescence wavelength, relatively serious scattering and high energy, and is easy to decompose components. Tb is good from a measurement methodology but not suitable for bioanalysis. Therefore, currently, Eu is widely used in bioassays.
The Chinese patent with the publication number of CN101382540A in the related technology discloses a platelet antigen antibody detection and cross matching solid phase anti-human globulin kit, belonging to the field of biotechnology. The purpose is to provide a solid phase anti-human globulin kit for detecting platelet antigen antibody and cross matching. It includes: u-shaped reaction plate, platelets, indicator cells, anti-human IgG, low-ion medium, anti-platelet serum, negative control serum and positive control serum.

After incubation in the plate with serum, the serum is washed to remove platelet antibodies if not, which bind to the platelets in the reaction plate if they are, anti-human IgG and indicator cells are added, and the indicator cells are bound to the platelet monolayer after centrifugation. Thus, a positive reaction indicating that the indicator cells are present in the bottom of the reaction well indicates that the blood contains platelet antibodies, while a negative reaction indicating that the indicator cells form red blood cell aggregates in the middle of the bottom of the reaction well indicates that the blood does not contain platelet antibodies.
