Vertical electrophoresis tanks are generally used for the analysis and size separation of nucleic acids, i.e., DNA and RNA.
The horizontal electrophoresis system is made of acrylic and comprises two buffer chambers, each containing an electrode. The apparatus consists of a casting tray, vertical electrophoresis tank, gel combs, electrodes, and a power supply. Conduct Science offers two different models of horizontal electrophoresis tanks. Each model has different sizes of casting trays and gel combs.

Vertical electrophoresis tanks are primarily used for nucleic acid and protein sequencing via vertical gel electrophoresis. In a vertical electrophoresis system, the gel matrix is cast vertically in a discontinuous buffer system, and two chambers, i.e., a top chamber and a bottom chamber, are employed.Ā
The vertical electrophoresis tanks employ a discontinuous buffer system comprising a top and a bottom chamber. The top chamber contains a cathode, and the bottom contains an anode. Electrodes present in both chambers generate the required electric field. A thin gel of less than 2mm is poured between two glass-mounted plates so touch that the upper part of the gel is submerged in the upper buffer chamber while the bottom of the gel is immersed in the lower buffer chamber. As soon as the electric field is applied, a small amount of buffer migrates through the gel from the upper chamber towards the lower chamber. As the buffer moves via the gel only, the experimenter has full control over the voltage gradients throughout the experiment. A vertical gel electrophoresis tank allows the researchers to achieve a more effective separation with greater resolution.
Unlike horizontal electrophoresis, vertical systems mostly use polyacrylamide gels with a smaller pore size (about 10-200nm). Acrylamide gel cannot be used for horizontal gel electrophoresis. The gel in the horizontal system must interact with environmental oxygen, and exposure of acrylamide to oxygen can inhibit acrylamide polymerization, thereby interfering with gel formation. In vertical electrophoresis, the buffer only migrates through the gel, and individual compartments do not get exposed to oxygen.
Moreover, acrylamide concentration controls the gel’s pore size and the degree of crosslinking. Pore size decreases as the total acrylamide concentration increases, and the amount of cross-linker is determined relative to the total acrylamide amount. On the other hand, pore size is parabolically related to crosslinking, i.e., at high and low cross-linking, pores are larger in size, whereas they are minimum in size at 4% crosslinking.
The vertical electrophoresis tank is made of acrylic and comprises an upper and a lower buffer chamber. The apparatus is equipped with two gel-cast frames and glass plates. The glass plates are accurately aligned to prevent gel leakage. There are two combs for creating wells. The built-in ridges in the combs isolate gel from the air and avoid polymerization reaction in the gel. Gel cast frame, gel cast stand, and electrophoresis core with high-quality and unique design are the features of the vertical electrophoresis tank offered by Conduct Science.

Protein Fraction Identification from Cowās Milk Casein Complex
Iukalo (2015) developed a vertical electrophoresis system to identify cow milk’s casein complex proteins. The researchers isolated individual casein protein fractions using preparative electrophoresis. They used a vertical electrophoresis tank to determine total casein’s fractional composition and homogeneity of its fractions. The polyacrylamide gel electrophoresis apparatus they used was Studier type, and it allowed change in the chambers’ geometric dimensions and the number of samples for simultaneous analysis. The electrophoresis system was optimized by reducing the dimensions of the electrophoresis chamber. The changeable dimensions of the electrophoretic chamber significantly reduced the time for identifying casein fractions. The scientists concluded that the method they developed could be useful for the robust analysis of milk and dairy products.Ā
Use in Western Blotting for the Detection of TLR4 Expression in Spinal Cord Tissue
Han et al. (2015) studied the effect of bone marrow mesenchymal stem cell (BMSC) on TLR4 (toll-like receptor 4) levels in four-week-old male SD rats. BMSCs were isolated and identified by immunocytochemistry. Then the scientists prepared animal models for BMSC transplantation, prepared spinal cord injury sites, and detected the presence of TNF-Ī± and IL-1Ī² using the RT-PCR method. A vertical electrophoresis tank was used for western blotting to detect TLR4 expression in the spinal cord tissue. In addition, about 30Āµg of proteins were fractionated using 12% sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The experimenters used GAPDH as a loading control. A gel documentation system was used for band identification, and computer software was used to quantify band intensities.Ā Ā
Vertical electrophoresis tanks are ideal for protein separation and identification. In vertical electrophoresis systems, the buffer can only migrate through the gel, allowing accurate voltage control during experiments. If the polyacrylamide gel with a small pore size is used, the vertical gel electrophoresis allows greater separation and resolution than horizontal systems. However, horizontal gel electrophoresis systems are sometimes preferred over vertical systems because of their ease of use.
