WebHow does gel electrophoresis work? During gel electrophoresis, charged macromolecules are loaded into a gel with an electric field. One end of the gel has a positive charge, and the other end has a negative charge. The macromolecules move from one end of the gel to the other end, due to their attraction to the opposite charge at that end. WebIn capillary electrophoresis the analogous expression for selectivity is. (12.7.6) α = μ ep,1 μ ep,2. where μ ep,1 and μ ep,2 are the electrophoretic mobilities for the two solutes, chosen such that α ≥ 1. We can often improve selectivity by adjusting the pH of the buffer solution.
WebThis is how gel electrophoresis pulls DNA through an agarose gel. Due to its negatively charged backbone, DNA is strongly attracted to a positive electrode. In agarose gel electrophoresis, the gel is oriented horizontally in a buffer solution.
