In the Native (Buffer) Gels electrophoresis it not possible to predict the behavior of a given protein in a buffer gel, but, because of the range of different charges and sizes of proteins in a given protein mixture, good resolution is achieved.

Gradient Gels electrophoresis are performed using gradient of  acrylamide Concentration that varies uniformly from, typically, 5% at the top of the gel to 25% acrylamide at the bottom of the gel.

There are two major advantages to running gradient gels. 

First, a much greater range of protein Mr values can be separated than on a fixed- percentage gel.

The second advantage of gradient gels is that proteins with very similar M r values may be resolved.

The higher no. of band will be observed in gradient gel electrophoresis comparison to uniform gel SDS and Native gel electrophoresis.

Isoelectric Focusing Gels is based on the separation of molecules according to their different isoelectric points at which the show zero electrophoretic mobility.
