WebDouble diffusion in Gel The Ouchterlony Technique : Both the ag and ab diffuse in a gel. 1. Agarose gel is placed on a solid surface (petri dish, glass slide, or plastic plate) and allowed to solidify. 2. Wells are cut into the gel and the agarose plug is removed. { Typically a central well is surrounded by multiple wells} WebM. Sasikala is an academic researcher from Crops Research Institute.

The antibodies in the antiserum react with both the antigens resulting in a smooth line of precipitate. The antibodies cannot distinguish between the two antigens. i.e., the two antigens are immunologically identical. See more In the ‘pattern of partial identity’, the antibodies in the antiserum react more with one of the antigens than the other. The ‘spur’ is thought to result from the … See more In the ‘pattern of non-identity’, none of the antibodies in the antiserum react with antigenic determinants that may be present in both the antigens, i.e., the two … See more WebAbstract.

The IEP begins by running a PAGE. Antisera against selected serum proteins are added to troughs running parallel to the electrophoresis track, forming precipitin arcs similar to those seen in an Ouchterlony assay (Figure 7). troll badge randomizer
