What is Two-Dimensional (Crossed) lmmunoelectrophoresis? Principle of Two-Dimensional lmmunoelectrophoresis The principle of two-dimensional (crossed) immunoelectrophoresis (2-D IEP) involves a two-step electrophoretic separation that permits antigen mixtures to be analysed and quantitated. In the first dimension the antigen (protein) mixture is loaded on an agarose gel and it is separated by electrophoresis by charge and mobility … Read more

What is Immunoelectrophoresis? Immunoelectrophoresis is defined as the separation of proteins by electrophoresis followed by their identification through immunologic (antigen-antibody) reactions. Immunoelectrophoresis Definition Immunoelectrophoresis is a biochemical technique that combines electrophoresis and antibody-antigen reactions to separate and identify proteins based on their antigenic properties. Objectives of Immunoelectrophoresis Principle of Immunoelectrophoresis The method is based on … Read more
