gel in Biological Dictionary

Gel

A gel is a solid, jelly-like material that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute crosslinked system, which exhibits no flow when in the steady-state. By... Environmental laboratory, consulting, engineering, and geophysical ...

Polyacrylamide Gel

A Polyacrylamide Gel is a separation matrix used in electrophoresis of biomolecules, such as proteins or DNA fragments. Traditional DNA sequencing techniques such as Maxam-Gilbert or Sanger methods used polyacrylamide gels to separate DNA fragments differing by a single base-pair in lengt...

Native Gel

Native Gel Electrophoresis is a technique used mainly in protein electrophoresis where the proteins are not denatured and therefore separated based on their charge-to-mass ratio. Native polyacrylamide gel electrophoresis is an electrophoretic separation method typically used in prot...

Denaturing Gel

A denaturing gel is a type of electrophoresis in which the native structure of macromolecules that are run within the gel is not maintained. For instance, gels used in SDS-PAGE will unfold and denature the native structure of a protein. In contrast to Native Gel Electrophoresis, quat...
