Preferred Label : Gel Electrophoresis;
NCIt related terms : Gel Electropheresis;
NCIt definition : 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.;
Alternative definition : CDISC: 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.;
