| rocket immunoelectrophoresis | A quantitative method for serum proteins which involves electrophoresis of antigen into a gel containing antibody; the technique is restricted to detection of antigens that move to the positive pole on electrophoresis. See: electroimmunodiffusion. Two-dimensional immunoelectrophoresis, a combination of conventional electrophoretic separation and electroimmunodiffusion; electrophoresis is first carried out, then the electrophoretic strip is placed on a second slide and an antibody-containing agarose solution is allowed to solidify adjacent to it; electrophoresis is then performed at right angles to the original separation. Synonym: crossed immunoelectrophoresis. (05 Mar 2000) |

| crossed immunoelectrophoresis | two-dimensional immunoelectrophoresis |
| immunoelectrophoresis | <technique> A two-step procedure which first involves the electrophoretic separation of proteins, followed by the linear diffusion of antibodies into the electrophoretic gel from a trough which extends through the length of the gel adjacent to the electrophoretic path. The antigen-antibody reactions produce precipitin arcs at positions where equivalence occurs. Although quantitation is subjective, an experienced eye candetermine not only the presence of the antigen but, through visual comparison to normal control sera, may discriminate relative increases or decreases of antigen by gauging the length and density of the precipitin arcs at positions established for specific antigens using known standards.

| immunoelectrophoresis, two-dimensional | Immunoelectrophoresis in which a second electrophoretic transport is performed on the initially separated antigen fragments into an antibody-containing medium in a direction perpendicular to the first electrophoresis. (12 Dec 1998) |
| countercurrent | 1. Flowing in an opposite direction. 2. A current flowing in a direction opposite to another current. (05 Mar 2000) |
| 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. (12 Dec 1998) |
| countercurrent exchanger | A system in which heat or chemicals passively diffuse across a membrane separating two countercurrent exchanger streams so that at each end the fluid leaving along one side of the membrane nearly resembles, in temperature or composition, the fluid entering the other; e.g., the venae comites in the arms serve as a countercurrent exchanger exchanger, the arterial blood serving to rewarm the cooler venous blood.

| countercurrent mechanism | A system in the renal medulla that facilitates concentration of the urine as it passes through the renal tubules. See: countercurrent exchanger, countercurrent multiplier. (05 Mar 2000) |
| countercurrent multiplier | A system in which energy is used to transport material across a membrane separating two countercurrent multiplier tubes connected at one end to form a hairpin shape; by this means a concentration can be achieved in the fluid in the hairpin bend, relative to the inflow and outflow fluids, that is much greater than the transport mechanism could produce between the two sides of the membrane at any point; e.g., the nephronic loops in the renal medulla act as countercurrent multipliers.
