Definitions related to gel electrophoresis (lab technique):
-
(gel electrophoresis) A method of separating large molecules (such as DNA fragments or proteins) from a mixture of similar molecules by electrophoretic filtration through a gelatinous matrix.CDISC TerminologyClinical Data Interchange Standards Consortium (CDISC), 2021
-
(gel electrophoresis) Electrochemical process in which macromolecules or colloidal particles with a net electric charge migrate in a gel under the influence of an electric current.CRISP ThesaurusNational Institutes of Health, 2006

(gel electrophoresis) Gel electrophoresis is a method of separating large molecules (such as DNA fragments or proteins) from a mixture of similar molecules by electrophoretic filtration through a gelatinous matrix. Subject to an electric field, each molecule in the sample mixture migrates through the matrix at a different rate, depending mainly on electrical charge and size, resulting in spatial separation within the matrix of each molecular species in the sample mixture. Agarose and acrylamide in a cylindrical tube or slab gel are commonly used media for electrophoresis of proteins and nucleic acids.NCI ThesaurusU.S. National Cancer Institute, 2021
