What is a 2D gel electrophoresis?

Two -dimensional (2D) gel electrophoresis is a method that scientists use to disassemble and analyze protein mixtures by first separation of protein strips along two different axes. It is a technique that is most often used in solving complicated or strong mixtures of proteins, often with overlapping proteins. The 2D gel electrophoresis varies from one -dimensional gel electrophoresis, as the former method uses the separation of proteins based on two different protein characteristics, while a single -dimensional gel electrophoresis usually separates proteins based on single characteristics such as protein size. Electric charge. This can be used in the advantage of scientists, as charged molecules can be separated by a size by a porous substrate, such as agarosis, using a gradient tension through a porous ion gel. Time, the molecules pass through this gel, towards the hub, which is opposite to the natural molecule charge. Small molecules and strongly charged molecules moveI bread than large molecules or proteins that are slightly charged. In a 2D gel electrophoresis, after separation of proteins using a single characteristic that creates a gradient, the gel can be turned sideways to separate the previous belts on the second characteristic.

2D Gel electrophoresis often uses molecular proteins hubs as one characteristic that can be divided into proteins with one component. Protein mass is another common characteristic used to separate proteins in 2D gel electrophoresis. After the proteins take place on the gel through a single strip in a single -dimensional gel electrophoresis, this gel can be shaken in centrifugation and quickly withdraw heavier proteins of mines than smaller, less massive proteins. The direction of the tension is perpendicular to the direction in which the proteins were drawn by gel due to attractiveness to the electric charge via the gradient voltage.

eLectrophoresis has many uses in molecular studies, including separation of proteins based on synthesized characteristics such as protein marking. Separation of protein -based protein is also used when proteins are marked with other molecules. This technique can be used with these protein complexes, as the marked proteins fall more easily through the gel than non -responded proteins.

While many separation gels in laboratories are made of agarosis, the separation of proteins using 2D gel electrophoresis is best done on polyacrylamide gels. These types of gels are used in western blots and other protein -based tests. Agarosis is more often used to separate DNA segments.
