ELECTROPHORESIS
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
The motion of charged particles in a colloid under the influence of an electric field; particles with a positive charge go to the cathode and negative to the anode
Synonyms:
cataphoresis; dielectrolysis; electrophoresis; ionophoresis
Classified under:
Nouns denoting natural processes
Hypernyms ("electrophoresis" is a kind of...):
action; activity; natural action; natural process (a process existing in or produced by nature (rather than by the intent of human beings))
Hyponyms (each of the following is a kind of "electrophoresis"):
immunoelectrophoresis (electrophoresis to separate antigens and antibodies)
carrier electrophoresis; paper electrophoresis (electrophoresis carried out on filter paper)
Derivation:
electrophoretic (of or relating to electrophoresis)
Context examples:
Protein-bound DNA is protected from the cleavage and can be analyzed by gel electrophoresis.
(DNA Footprinting, NCI Thesaurus)
A computer-implemented image processing method and apparatus for normalizing gel electrophoresis images.
(Gel Warping Algorithm, NCI Thesaurus)
An electrophoresis gel composed of agarose dissolved in an aqueous buffer.

Nuclear extracts contain proteins in nuclear compartment of the cell and are used to monitor transcription factor activation in a variety of standard protocols, including electrophoresis mobility shift assay (EMSA), DNA footprinting, Western blotting and preparative purification of nuclear proteins.
(Nuclear Extract, NCI Thesaurus)
Recurrence of malignancy following hematopoietic cell transplantation, based on one or more of the following parameters: marrow morphology, flow cytometry, cytogenetic studies, including fluorescence in situ hybridization, electrophoresis, immunofixation assays, and polymerase chain reaction-based assays for disease markers, or imaging results.

When the neural signal of a seizure is detected by the electrodes, the ion pump is activated, creating an electric field that moves the drug across an ion exchange membrane and out of the device, a process known as electrophoresis.
(Electronic device implanted in the brain could stop seizures, The Titi Tudorancea Bulletin)
A procedure in which multilocus band patterns of a DNA sample are generated by digestion of the DNA with restriction enzymes followed by electrophoresis and visualization by hybridization with probes specific for repetitive sequences.
(DNA Fingerprinting, NCI Thesaurus)
RNA extracted from a sample was denatured and separated by slab gel electrophoresis, then blotted on to a nitrocellulose or nylon sheet and hybridized with labeled DNA or RNA that is complementary to the desired RNA, whose presence is subsequently indicated by autoradiography or other visualization techniques.
(Northern Blotting, NCI Thesaurus)
Electrophoresis may be used to help diagnosis certain diseases.
(Electrophoresis, NCI Dictionary)
After the gel electrophoresis, the gel is scanned with the excitation wavelength of each dye and the imges are superimposed, allowing detection of changes in protein abundance between samples.
