The invention discloses a full-range C-reactive protein detection kit, which comprises a reagent R1 and a reagent R2. The reagent R1 is a proper buffer solution; the reagent R2 is formed by the following steps: sensitizing two or more styrene latex with different average grain diameters by using an anti-human C-reactive protein antibody; placing the sensitized styrene latex with the different average grain diameters into the proper buffer solution respectively to form reagents; and finally mixing the reagents in different proportions, wherein the reagent R2 contains 0.8 to 3.5 mg / mL of the styrene latex combined with the anti-human C-reactive protein antibody. The full-range C-reactive protein detection kit not only can measure lower CRP content but also can measure high CRP content, and has the advantages of high sensitivity and stability and accurate measurement.

The invention provides a nucleic acid aptamer-based lung metastatic osteosarcoma tissue immunofluorescence kit. The nucleic acid aptamer-based lung metastatic osteosarcoma tissue immunofluorescence kit comprises a), an antigen repairing liquid; b), a washing liquid; c), a nucleic acid aptamer dilution liquid; d), a blocking liquid. In applications, Cy5 labelled nucleic acid aptamer is taken as a fluorescence probe for labeling of paraffin embedded lung metastatic osteosarcoma tissue. The nucleic acid aptamer is capable of realizing specific combination with lung metastatic osteosarcoma cells,and combination with other cells is impossible to realize, so that the nucleic acid aptamer is taken as a novel molecule probe with high specific recognition capacity on lung metastatic osteosarcoma,and possesses important research meaning in early stage diagnosis and treatment of osteosarcoma susceptible to pulmonary metastasis. In applications, paraffin section immunofluorescence dyeing is adopted, pathological diagnosis on lung metastatic osteosarcoma tissue can be realized without low temperature storage, the specificity is high, the sensitivity is high, operation is simple, equipment requirement is low, positioning performance is excellent, and reality meaning in domestic popularization is achieved.

The invention discloses a room-temperature phosphorescence detection method of lysozyme and an application, belongs to the technical field of detection of lysozyme, and can solve the problems of complex detection process, high cost and strong interference of lysozyme at present. A prepared Mn:ZnS room-temperature phosphorescence quantum dot modified with beta-cyclodextrin is used as a phosphorescence probe, a lysozyme nucleic acid aptamer is used as a molecular recognition unit, and analysis and detection of the lysozyme can be realized by detecting the room-temperature phosphorescence intensity of a system after the lysozyme is added. The response range of the phosphorescence detection system to the lysozyme is 5.5 nM-44.4 nM and the detection limit is 0.54 nM. The method can be used fordetecting lysozyme in serum, urine samples, honey and wine, and the complex sample pretreatment process during detection can be avoided. A deoxidant and an inducer are not required to be added for production of room-temperature phosphorescence, and interference of background fluorescence and scattered light of actual samples can be avoided.
