Example Embodiment

[0039] The following describes the implementation of the present invention through specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0040] The present invention intends to use the prostate specific membrane antigen (Prostate Specific Membrane Antigen, PSMA) nucleic acid aptamer (aptamer) to specifically recognize prostate cancer PSMA(+) exosomal subgroups, and aggregate the fluorescent molecule TPE-TA fluorescent reporter group Together with the Graphene Oxide (GO) fluorescence quenching group, it forms a label-free "Turn-on" fluorescent reporter system, and uses this to c...

Abstract

The invention discloses a kit used for tumor exosome nanometer fluorescence detection and application of the kit. The kit comprises an identification element, a fluorescence reporter group and a fluorescence quenching group. The kit and the application thereof not only confirm that the PSMA on the human plasma source exosome can be used as a biomarker for identifying a health volunteer and a prostate cancer patient but further proves that the influence of normal cell source exosome in a clinical plasma specimen on a detection result can be effectively avoided through the method, and the kit has good anti-interference capability and a relatively large clinical application potential in the aspect of prostate cancer PSMA(+) exosome subgroup analysis.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a "Turn-on" tumor exosome nano-fluorescence detection kit based on nucleic acid aptamers and aggregation-induced luminescent materials and its application. Background technique [0002] In recent years, the incidence of prostate cancer in my country has been increasing year by year. The proportion of newly diagnosed patients in most regions is higher than that in Europe and the United States. Prostate cancer has the characteristics of rapid development and easy metastasis. Timely diagnosis and treatment before symptoms and signs appear can significantly Improve prognosis and prolong patient survival. Therefore, it is particularly important to establish sensitive, specific, non-invasive, convenient and rapid detection methods for early screening, diagnosis or monitoring of prostate cancer to control the development of prostate cancer and improve the quality of life of patients.
