electrophoretic mobility

[i¦lek·trō·fə′red·ik mō′bil·əd·ē]
(biochemistry)
A characteristic of living cells in suspension and biological compounds (proteins) in solution to travel in an electric field to the positive or negative electrode, because of the charge on these substances.

Because electrophoretic mobility depends chiefly on size, IMA data are expressed in terms of particle diameter, which corresponds to the calculated diameter of a singly charged, spherical particle with the same electrophoretic mobility (24-26).
As previously discussed, such differences could be related to differences in electrophoretic mobility between certain proteins, depending on which technique is used.
Electrophoretic mobility of the clay fractions, artificial mixtures, and adsorbed mineral samples was measured in the pH range 3.
These results support the idea that isozyme present in quail testes constitute extreme type LDH and that although they have nearly identical electrophoretic mobility.
2]] concentration resulted in a gradual increase in electrophoretic mobility of reacted HA, indicating a [[H.
res] retained the electrophoretic mobility and glycoform ratio associated with BSE-related [PrP.
Recently, electrophoretic mobility shift assay (EMSA) was used to determine protein binding characteristics in the MLL bcr.
Mitochondrial DNA and mRNA from peroxisome proliferator-activated receptor gamma and alpha (Pparg and Ppara) and carnitine palmitoyl transferase 1a (Cpt1a), as well as several transcription factors involved in mitochondrial biogenesis, were evaluated by real-time PCR or electrophoretic mobility shift (EMSA) assay.
As shown Figure 3, nuclear extracts from PMA-stimulated EL4 T cells (treated with AII fraction) and nuclear extract from nonstimulited EL4 T cells (treated with Sill fraction) exhibited strong NF-AT-binding activity in the electrophoretic mobility shift assays using a labeled oligonucleotide containing a consensus NF-AT site.
Studies [7-10] revealed that the nature of the anionic part of ILs affects slightly the electrophoretic mobility and the IL concentration influences the general electrophoretic mobility of the separation media.
The effective surface potential, called zeta potential, is commonly determined from electrophoretic mobility measurements for particles moving in the solution owing an electric field applied between two electrodes (Adamson and Gast, 1997; Masliyah and Bhattacharjee, 2006).
Before electrophoresis, the proteins are denatured in a detergent called sodium dodecyl sulfate (SDS), which supplies a uniform negative charge for electrophoretic mobility of the proteins.
