Hybridoma cell strain secreting anti-serine phosphorylated tau protein monoclonal antibody

Abstract

The invention belongs to the field of immunodetection, and discloses two hybridoma cell strains secreting anti-serine phosphorylation tau protein monoclonal antibodies, and the hybridoma cell strains used for secreting p-Tau 396, 404 monoclonal antibodies, the hybridoma cell strains are preserved in the China Center for Type Culture Collection (CCTCC), and the preservation numbers are respectively CCTCC NO: C2020219 and CCTCC NO: C2020218. According to the invention, two hybridoma cell strains capable of secreting novel p-Tau 396, 404 monoclonal antibodies are provided, and the monoclonal antibodies capable of specifically recognizing human p-Tau 396, 404 and aggregates thereof can be prepared by using the hybridoma cell strains, so that the problem of lack of antibodies capable of simultaneously targeting p-Tau 396, 404 at present is solved. The two monoclonal antibodies provided by the invention can be further applied subsequently to prepare a high-specificity and high-sensitivity p-Tau 396, 404 detection kit, the immunological treatment of specific targeting p-Tau 396, 404 is developed, the disease progress is slowed down, and the blank of the current immunological treatment of targeting p-Tau 396, 404 is filled up.

Description

technical field [0001] The present invention belongs to the field of immunoassay, and more specifically, relates to two kinds of hybridoma cell lines secreting anti-serine phosphorylated tau protein monoclonal antibody, that is, two kinds of Tau protein capable of secreting anti-human phosphorylated serine at 396 and 404 positions (p-Tau 396,404 ) Hybridoma cell lines of monoclonal antibodies. Background technique [0002] Alzheimer's disease (AD) is a neurodegenerative disease with insidious onset and progressive development. Clinically, it is characterized by comprehensive dementia such as memory impairment, aphasia, apraxia, agnosia, impairment of visuospatial skills, executive dysfunction, and personality and behavior changes. The etiology of most Alzheimer's diseases is still unknown, and only Genetic differences have been identified in 1% to 5% of cases. Alzheimer's disease is the most common cause of dementia and is responsible for 60% to 80% of dementia cases worl...
