Abstract

The invention relates to the technical field of detection kits, and particularly discloses an ELISA kit for quantitatively detecting tight junction related protein Occludin. The kit comprises an elisaplate coated with an Occludin coated antibody, HRP labeled goat anti-rabbit IgG, a rabbit anti-human Occludin polyclonal antibody, a washing solution, a sample diluent, a color developing agent, a stop solution, a quality control material and a standard substance, the kit is based on the Occludin coated antibody and the goat anti-rabbit IgG, and an ELISA method for Occludin protein detection is established by adopting a double antibody sandwiching method. The kit overcomes the defects in the prior art, can be used for effectively detecting the level of Occludin protein in a serum sample, is simple, convenient and rapid to operate, has good detection accuracy and precision, high specificity, good sensitivity and good stability, and can be used for rapidly and timely helping to diagnose theillness state and monitor prognosis.

Description

technical field [0001] The invention relates to the technical field of detection kits, in particular to an ELISA kit for quantitatively detecting tight junction-related protein Occludin. Background technique [0002] The blood-brain barrier (BBB) ​​is an important structure to maintain the stability of the unique internal environment of the central nervous system, and it is the premise and basis for the neurons of the central nervous system to carry out various physiological activities. The basic structure of the blood-brain barrier includes: brain microvascular endothelial cells and their tight junctions (TJ), endothelial basement membrane and astrocyte terminal feet. Among them, brain microvascular endothelial cells and their tight junctions are the core structure of the blood-brain barrier. [0003] The basic ultrastructural characteristics of tight junctions in various tissues and organs are similar, and they are all manifested as: under the transmission electron micros...
