Two-dimensional gel electrophoresis or 2D-PAGE is the primary technique for proteomics work. It separates the complex mixture of samples using two different properties of the proteins. In the first dimension, proteins are separated by the pI value and in the second dimension by the relative molecular weight.

Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size. In gel electrophoresis, the molecules to be separated are pushed by an electrical field through a gel that contains small pores.

EPS horizontal gel electrophoresis offers many advantages for nucleic acid separation and remains today one of the mainstays of molecular biology. EPS range offers the most comprehensive and versatile range of horizontal gel electrophoresis units currently available for low- and high- throughput DNA and RNA applications.

Easier to assemble, leak-proof, and with a four-gel capacity that doubles the output of the traditional cell, the Mini P-4 cell combines traditional features with higher throughput and even greater reliability.

Vertical gel electrophoresis is a slightly trickier technique where the gels are cast in a vertical direction. A discontinuous buffer system is used in this technique where the top compartment has cathode and the bottom compartment has anode.
