by Abnova - SDS-PAGE is a technique used to separate proteins according to their electrophoretic mobility. SDS gel electrophoresis of samples have identical charge per unit mass due to binding of SDS results in fractionation by size, visualize the separated proteins, or process further application.

Electrophoresis is the movement of an electrically charged substance under the influence of an electric field. This movement is due to the Coulomb force, which may be related to fundamental electrical properties of the body under study and the ambient electrical conditions by the equation given below. F is the Coulomb force, q is the charge carried by the body, E is the electric field. This movie...

Introduction: Transcript Studying the human genome - the complete set of human genes - is a way of studying fundamental details about ourselves. The three billion letters of the human genome are written using the four-letter alphabet of DNA. The DNA is divided among 23 pairs of chromosomes that are found in each of the trillions of cells in our bodies. In 2003, The Human Genome Project produced a...

The DNA molecules produced during the sequencing reaction are separated from each other by a process called electrophoresis. DNA molecules are negatively charged. The sequencing machine sets up an electric field; all the DNA moves through a porous gel toward the positive electrode. The gel acts like a sieve; shorter DNA fragments move more quickly through the holes of the gel than do larger DNA fr...
