In Ouchterlony double diffusion, both antigen and antibody are allowed to diffuse into the gel. This technique can be used to test the similarity between antigens, for example in a study of evolution. Antigens from different species are loaded into two wells and ...

WebA simple, rapid method, based on the Oudin single gel diffusion technique, is described for the quantitative assay of staphylococcal enterotoxin B. The method yields reproducible results without close control of such assay variables as temperature, antiserum dilution, and assay time, provided that the ionic strength is maintained above 0.2 N sodium chloride … WebOudin single diffusion Radial immunodiffusion (single) Ouchterlony double diffusion. antibody (serum) is added to an agarose and placed in a test tube. Antigen is layered over the gelled antibody and diffuses down. As antigen moves down the gel, a precipitin band is formed as a function of the time elapsed, concentration of antigen in solution ... hht mutation database
