What is another name for one-dimensional single electroimmunodiffusion?

One-dimensional single electroimmunodiffusion is commonly referred to as Rocket electrophoresis because of the characteristic appearance of the precipitin lines that resemble rocket shapes on the gel. This method involves the simultaneous diffusion of antigens and antibodies under an electrical field, leading to the formation of a precipitate where the antigen and antibody meet in optimal proportions. The length of the "rocket" is directly proportional to the concentration of the antigen, making it a useful quantitative technique in immunology.

Rocket electrophoresis is particularly valuable because it combines the principles of immunodiffusion and electrophoresis, allowing not only for the identification of specific antigens but also for the quantification of their concentrations in a sample. This unique approach distinguishes it from other forms of electrophoresis offered in the choices.

The other terms listed refer to different techniques: Capillary electrophoresis is a technique that separates ions based on their speeds in an electric field, often using thin capillaries. Zone electrophoresis refers to a method where molecules are separated in zones according to their charge and size but does not adopt the specific mechanism that creates the 'rocket' morphology. Two-dimensional electrophoresis involves separating proteins by isoelectric point and then by molecular weight,
