Abstract

The invention relates to a treponema pallidum (TP) antibody test kit based on the flow microspheric carrier technology and a preparation method and detection method thereof, belonging to the technical field of immunoassay medical diagnosis. The preparation method comprises the following steps: using TP recombinant antigen to coat heavy polymer microsphere, using bovine serum albumin to seal empty binding site, preparing specific TP probe-heavy polymer microsphere; performing coculture with a sample to be tested to capture TP antibody, washing and centrifuging to remove the unbound TP antibody, then adding fluorescently-labeled anti-human IgG or IgM antibody; and using a flow cytometry to detect the fluorescence intensity of the microsphere, and performing qualitative or quantitative analysis to the tested antibody. The method has the advantages of high sensitivity and specificity and good stability and can be used to perform microanalysis or multivalent analysis to the sample.

Description

technical field [0001] The invention relates to a Treponema pallidum (TP) antibody detection kit based on flow microsphere carrier technology and a preparation and detection method thereof, belonging to the technical field of immunoanalysis medical diagnosis. Background technique [0002] The incidence of syphilis in my country has been increasing year by year in recent years. In April 2010, the Ministry of Health announced that among the 27 types of legally reported Class A and Class B infectious diseases in the country, the top five diseases were viral hepatitis, tuberculosis, dysentery, syphilis and influenza A (H1N1), among which syphilis Ranked third, fourth in 2009, and fifth in 2005. [0003] Syphilis is a chronic systemic infectious disease not limited to the skin or reproductive system that occurs after the human body is infected with Treponema pallidum, and is mainly transmitted through sexual contact, mother to child, and blood. At present, the detection of seru...
