Abstract

The invention discloses application of a blood serum CCKBR (Cholecystokinin B Receptor) to a glioma diagnosing marker and a double-antibody sandwich method ELISA (Enzyme-linked Immuno Sorbent Assay) kit for diagnosing glioma. The invention discloses a novel biomarker for diagnosing the glioma and especially has a very important effect and clinical application value on early warning and early diagnosis of the glioma. Meanwhile, the invention also establishes an enzyme-linked immuno diagnosing system based on a double-antibody sandwich principle and a glioma diagnosing kit is developed; detection of the CCKBR can be rapidly and accurately carried out and rapid auxiliary diagnosis can be carried out on primary glioma of each stage (especially an early stage); the kit has important clinical application value. The kit disclosed by the invention has the advantages of simplicity in operation, stable reagent, good repeatability, strong specificity, high sensitivity and the like and has a widemarket prospect of being easily popularized and applied in a large range.

Description

technical field [0001] The invention belongs to the technical field of biomedicine. More specifically, it relates to a double-antibody sandwich ELISA detection method and kit for diagnosing adult glioma. Background technique [0002] The term "glioma" refers to tumors originating from glial cells, including astrocytomas, oligodendrogliomas, oligoastrocytomas, and ependymomas, among others. Gliomas are the most common primary intracranial tumors. The WHO classification of tumors of the central nervous system classifies gliomas into grades I to IV, of which grades I and II are low-grade gliomas, and grades III and IV are high-grade gliomas. grade glioma. Gliomas can be pathologically diagnosed and classified according to tumor location, cell morphology, arrangement, differentiation characteristics, immunophenotype, ultrastructural and molecular genetic changes. [0003] Histomorphological observation is still the basis of pathological diagnosis, but molecular biological mar...
