What is Two-Dimensional (Crossed) lmmunoelectrophoresis? Principle of Two-Dimensional (Crossed) lmmunoelectrophoresis The principle of Two-Dimensional (Crossed) Immunoelectrophoresis involves the combination of two distinct electrophoretic steps to separate and identify proteins based on their charge, size, and antigen-antibody interactions. The technique consists of the following steps: The principle of Two-Dimensional Immunoelectrophoresis exploits the migration characteristics of proteins … Read more

What is Immunoelectrophoresis? Immunoelectrophoresis is a biochemical approach for protein separation and characterization that is based on electrophoresis and antibody-antigen interactions. It uses immunodiffusion and electrophoresis techniques to identify and analyse specific antigens within a protein mixture. The immunoelectrophoresis procedure begins with electrophoresis, which separates the antigen mixture into its distinct components. This is accomplished … Read more

What is Polyacrylamide Gel Electrophoresis (PAGE)? Definition of Polyacrylamide Gel Electrophoresis (PAGE) Polyacrylamide Gel Electrophoresis (PAGE) is a technique used to separate and analyze proteins or nucleic acids based on their mobility in a porous polyacrylamide gel matrix under the influence of an electric field. Types of Polyacrylamide Gel Electrophoresis (PAGE) There are several types … Read more

What is SDS-PAGE? Definition of SDS-PAGE SDS-PAGE is a technique used to separate proteins based on their molecular weight by using a gel matrix and the denaturing agent sodium dodecyl sulfate (SDS). Overview of SDS PAGE SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) is a popular method for studying protein mixtures. By sorting proteins depending on … Read more
