Electrophoresis
Electrophoresis of positively charged particles (cations) is sometimes called cataphoresis, while electrophoresis of negatively charged particles (anions However, Debye length must be important for electrophoresis, as follows immediately from Figure 2, "Illustration of electrophoresis retardation". wikipedia.org

Gel electrophoresis (article) | Khan Academy
Gel electrophoresis is a technique used to separate DNA fragments (or other macromolecules, such as RNA and proteins) based on their size and charge. Electrophoresis involves running a current through a gel containing the molecules of interest. Based on their size and charge, the molecules will travel through the gel in different directions or at different speeds, allowing them to be separated ...

Gel electrophoresis and foam ![Foam appeared while DNA electrophoresis]( I've never seen this kind of thing happen. What might trigger this??
Some electrophoresis buffers do contain detergent.

Procedure of diagonal electrophoresis I am learning protein sequencing and it seems that diagonal electrophoresis is a common method in the identification of disulphide bonds (S-S) exist between polypeptides in a prot...
You probably don’t _need_ to oxidize the disulfide bonds rather than reduce them. Performic acid has some potential advantages: * The oxidation products can’t spontaneously reform a disulfide bond whereas the reduction products from a thiolate reductant can. * Oxidation by performic acid causes a si...

Hemoglobin electrophoresis
Procedure The test uses the principles of gel electrophoresis to separate out the various types of hemoglobin and is a type of native gel electrophoresis Newer alternatives to conventional hemoglobin electrophoresis include isoelectric focusing, capillary zone electrophoresis, and high-performance liquid wikipedia.org

Which comes first, PCR or Gel electrophoresis? If I want to find out wither a group of patients have the abnormal BCR-ABL cancer gene, how do I benefit from the PCR and the gel electrophoresis techniques? I'm kinda lo...
That is what the electrophoresis is for.

Affinity electrophoresis
Cross electrophoresis, the first affinity electrophoresis method, was created by Nakamura et al. The methods include the so-called electrophoretic mobility shift assay, charge shift electrophoresis and affinity capillary electrophoresis. wikipedia.org

Is AT or GC content important in electrophoresis? Will it make a difference in running speed if we run samples of same no of bases but different AT - GC content ?
It does make a difference on polyacrylamide. A and C are faster while G and T are slower. Image from publication: !enter image description here The "standards" are AAA/TTT/GGG/CCC molecules.

Pump to separate protein/DNA instead of electrophoresis? I know that DNA molecules or proteins can be separated in electrophoresis because the electrical charge is used to pull the DNA through the gel. So instead of u...
I am old enough to remember running vertical agarose gel electrophoresis overnight, and these gels would collapse under normal pressure to about 2/3rds

4.2. TWO-DIMENSIONAL GEL ELECTROPHORESIS. Two-dimensional electrophoresis is one of the most commonly used techniques in proteomics. The basic principles of two-dimensional gel electrophoresis (2D-GE) remain the same since its introduction in 1975 (3,4), namely, the initial separation of proteins by isoelectric focusing (IEF, first dimension) followed by an orthogonal separation via sodium ...
