A precipitin is an antibody which can precipitate out of a solution upon antigen binding. [1] The precipitin reaction provided the first quantitative assay for antibody. The precipitin reaction is based upon the interaction of antigen with antibody leading to …

6 天之前 · The precipitin test is valuable for diagnosing and monitoring conditions, from infectious diseases to immune disorders. It identifies specific antigens associated with pathogens like bacteria, viruses, and fungi, aiding in early detection, especially in immunocompromised patients. It also detects antibodies against pathogens, helping diagnose ...

A precipitin is a reaction used for the qualitative identification of antigens and antibodies by observing the formation of a visible immune precipitate at the interface of a dilute solution of antigen and immune serum in a test tube.

Precipitin is a complex lattice between an antibody of a given specificity and its cognate antigen. From: Forensic Science Reform, 2017

The meaning of PRECIPITIN is an antibody that forms a precipitate when it unites with its antigen.

The precipitin reaction occurs when a precipitating antibody combines with its conjugate antigen to produce an insoluble proteinaceous immune complex that can be detected under appropriate oblique lighting conditions by the naked eye or by the use of general protein stains such as Coomassie blue or amido black.

A precipitin assay is a test that shows the reaction between an antigen (a molecule that triggers an immune response) and an antibody (a protein produced by the immune system to fight antigens). When these two interact at the right ratio, they form a visible structure called a precipitin, which looks like a fine white line in some setups.

precipitin reaction a reaction involving the specific serologic precipitation of an antigen in solution with its specific antiserum in the presence of electrolytes. The reaction is used in the typing of pneumococcus strains, in testing whether blood is human or animal, and for diagnostic purposes.

Precipitin reaction, specifically the ring test, is a classic immunological assay used to detect the presence of antigens or antibodies in a sample. It is based on the principle of antigen-antibody interaction, which forms a visible precipitate.

Precipitin is an antibody that reacts with a soluble antigen to form a visible precipitate. It is commonly used in immunological assays to detect the presence of specific antigens.
