Rocket electrophoresis (also referred to as electroimmunoassay or electroimmunodiffusion) is a simple, quick, and reproducible method for determining the concentration of a specific protein in a protein mixture. In this experiment, students are introduced to the use of immunoelectrophoresis to separate and characterize a mixture of proteins and examine the specificity of the antigen-antibody interaction. Using a 5 μl pipette, 5 μl of control and sample is applied across each Jun 10, 1986 · Combining the electrophoretic principles of counter current immunoelectrophoresis and deflection of line precipitates in line immunoelectrophoresis provides a new technique for quantitative determination of antibodies against specific antigens (CCLD electrophoresis), even if no purified antigen or m … Counter-current immunoelectrohporesis is a rapid sensitive method for detecting pneumococcal capsular antigens in sputum. 4 Plate HeightEquation 15 2. Test your understanding of the process and its applications in laboratory settings. • It is also known as electroimmunoassay or electroimmunodiffusion. Topics include the principles of movement within the gel medium, the formation of precipitin lines, and test interpretation. The technique is used to check antisera for the presence and specificity of antibodies for a particular antigen. Counter immunoelectrophoresis and agar gel immunodiffusion may also be used. 1 Principles ofChromatography 11 2. Aplicació i avantatges de la immunoelectroforesi a contracorrent. tPro~ of Pediabics.
