How to Make an Electrophoresis Gel: 9 Steps (with Pictures)

28 02 2020Electrophoresis is the term used for the study of the way charged particles move through a medium when subjected to an electrical field The particles will travel through the gel at different speeds depending on the charge carried by the particle and the size of the particle that must push through the somewhat restrictive medium

Exclusion of spheres by agarose gels during agarose gel

Agarose gel electrophoresis of spheres (radius = R) has been used to determine the effective radius (P E) of the pores of an agarose gel (percentage of agarose in a gel = A) The value of P E at a given A was taken to be the R of the largest sphere that enters the gel When log P E is plotted as a function of log A the results can be represented by: P E = 118A-0 74 for 0 2 ≤ A ≤ 4 0 (P E

Western Blot Protocols part 1

The pore size of a gel is determined by two factors: the total amount of acrylamide present and the amount of cross-linker As the percentage of acrylamide increases the pore size decreases With cross-linking 5% gives the smallest pore size Any increase or decrease in cross-linking percentage increases or decreases the pore size Gels are designated as percent solutions and will have two

Gel Filtration

Gel filtration separates molecules according to differences in size as they pass through a gel filtration medium packed in a column Unlike ion exchange or affinity chromatography molecules do not bind to the chromatography medium so buffer composition does not directly affect resolution (the degree of separation between peaks) Consequently

Zeolite adsorption

Zeolite does not have a linear adsorption curve In other words adsorption capacity is not reduced greatly for low VOC concentrations It is thus more suitable for working with low end concentrations than activated carbon or polymer Zeolites can be obtained with pore sizes between 0 3 – 3 nm This pore size is uniform for one type of

What Percentage Agarose Is Required For Electrophoresis?

Resolving fragments which have a similar size can be tricky to do on agarose gels For example a 30 bp difference in size between two fragments But there are a few tricks you can do to help with this Use a high percentage agarose gel Between 2 00% and 3 00% should help Higher concentration gels have a better resolving power Create a larger agarose gel If the gel is longer this means
