Abstract

The invention relates to the field of medical detection, and discloses a CIC (circulating immune complex) antigen buffer solution dissociation neutralizer for an immune complex buffer dissociation agent. Every 1L of the CIC antigen buffer solution dissociation agent comprises 16-24g of trometamol, 5.7-8.6g of sodium chloride, 100-500 mu l of liquid biological preservative and the balance of distilled water. The method for detecting CIC by using the immune complex buffer dissociation agent establishes a standard operation process for specifically detecting the antigen in the CIC, which is the problem that can not be solved by the existing CIC detection methods. The immune complex buffer dissociation agent has the technical characteristics of high specificity and sensitivity, high efficiency and favorable repetitiveness, is free from interference, and can perform quantitative or qualitative detection. The immune complex buffer dissociation agent is used for detecting CIC in body fluid samples of patients with infectious diseases, incretion metabolic diseases, autoimmune diseases and part of neoplastic diseases.

Description

technical field [0001] The invention relates to the field of medical detection, in particular to a CIC antigen buffer dissociation neutralizer used for immune complex buffer dissociation agents. Background technique [0002] After bacteria, viruses and other pathogens invade the body or allergens (antigens, including self-antigens) stimulate the body to generate an immune response, and then produce specific immune effector cells or antibodies, and specifically bind to the antigen, the resulting complex is called Immune complexes (also known as antigen-antibody complexes, immune complexes, IC) mainly include IgG, IgM, IgA, and IgE type immune complexes, among which IgG and IgM are the most common. Due to the different ratios of antigen and antibody, the formed IC molecules have different sizes, usually in three forms: First, when the ratio of antigen to antibody is appropriate, large insoluble ICs (greater than 19S) are formed, which are easily captured, phagocytized and clea...
