When the first dimension is a IEF (isoelectric focusing) and the second dimension is a native electrophoresis (anodal or cathodal - instead of the SDS-dimension of a 2D), this combination is called “Double Native Electrophoresis”.

The second dimension does not display the molweights of the proteins, but 2 proteins with the same isoelectric point and different secondary or tertiary structure will be separated.
