[Sensitivity and specifitivity of the counterimmunoelectrophoresis for determination of precipitating antibodies (author's transl)]. 1978

P Luther, and K C Bergmann

Counterimmunoelectrophoresis (C.I.E.) is suitable for routine-work in clinical medicine to give quantitative evidence of precipitating antibodies. Sensitivity of this method is high (lowest level being 200 to 400 ng albumin/ml serum) and range of evidence being very broad (14-15 titer steps). The direction of migrations of proteins with anodal migration (Ig) is changed by carbamylation. The experience gained in more than 3,000 investigations, concerning methods and evaluation of the results, is reported in detail. Counterimmunoelectrophoresis is superior to immunoelectrophoresis and double diffusion (Ouchterlony) due to its higher sensitivity and to RAST or RIST by reason of its lower costs.

UI MeSH Term Description Entries
D007070 Immunoglobulin A Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions. IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA
D007074 Immunoglobulin G The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B. Gamma Globulin, 7S,IgG,IgG Antibody,Allerglobuline,IgG(T),IgG1,IgG2,IgG2A,IgG2B,IgG3,IgG4,Immunoglobulin GT,Polyglobin,7S Gamma Globulin,Antibody, IgG,GT, Immunoglobulin
D007122 Immunoelectrophoresis A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D011234 Precipitins Antibodies which elicit IMMUNOPRECIPITATION when combined with antigen. Immune Precipitates,Precipitates, Immune
D003377 Countercurrent Distribution A method of separation of two or more substances by repeated distribution between two immiscible liquid phases that move past each other in opposite directions. It is a form of liquid-liquid chromatography. (Stedman, 25th ed) Chromatography, Countercurrent,Countercurrent Chromatography,Distribution, Countercurrent
D003485 Cyanates Organic salts of cyanic acid containing the -OCN radical. Cyanate
D000941 Antigens Substances that are recognized by the immune system and induce an immune reaction. Antigen
D012709 Serum Albumin A major protein in the BLOOD. It is important in maintaining the colloidal osmotic pressure and transporting large organic molecules. Plasma Albumin,Albumin, Serum
