Description

Novel detection reagent card shell

Technical Field

The utility model relates to a detect reagent card technical field, especially relate to a novel detect reagent card shell.

Background

A test paper strip shell rapid diagnosis technology is initially applied to the detection of urine and serum chorionic gonadotropin, is continuously developed with the scientific technology of China, and is widely applied to the production of human immunodeficiency virus antibody detection kits.

The existing portable check-up detection, the test paper generally adopts immune colloidal gold chromatography technology of double antibody sandwich mode, after the test paper is dripped with sample solution, the antigen in the solution crawls to the position of the binding pad along with the solution, reacts with the colloidal gold labeled antibody 1 therein to form red antigen-antibody complex, then the chromatography moves forward continuously, at the T position detection line of the observation window, the antigen in the red immune complex is captured and retained by the pre-coated antibody at the T position, and a red line is formed gradually as the retention of the red complex increases, therefore, the sample solution can be judged to be positive according to the appearance of the red T line, if no antigen exists in the sample, the immune antigen-antibody complex is not formed, the immune antigen-antibody complex flows through the T position, no capture and retention occurs, the T position remains white, and the sample is judged to be negative.

The test paper is placed in the card shell, through instiling into the sample, runs through test paper's change and knows the testing result, and the card shell of fixed test paper is disposable product, can be abandoned after the use, can't obtain reuse, causes the waste of resource, and we propose a novel detect reagent card shell to solve current problem for this reason.
