What is the difference between Vertical and horizontal Gel Electrophoresis?

 

Gel electrophoresis is a method for separating proteins and nucleic acids (DNA or RNA) based on their molecular weight. Forensics, immunizations, DNA profiling, and other applications in the life sciences are all examined in laboratories using vertical electrophoresis equipment.

According to some professionals, the vertical gel electrophoresis method is considered to be more advanced than the horizontal gel electrophoresis approach. It works according to the fundamentals of gel electrophoresis. This technique takes use of an erratic buffer. The cathode is located in the top chamber, while the anode is in the lower chamber. The electrodes present in each compartment create the crucial electric field. A thin gel layer lies between the two glass plates.

Difference between Vertical and horizontal Gel Electrophoresis

Vertical Gel Electrophoresis Horizontal Gel Electrophoresis Used to separate nucleic acids (50 – 20,000 bp) Used to separate proteins (5 – 250,000kDa) Utilize agarose gel Utilize polyacrylamide gel Run under native condition Run under denaturing condition Only 1 gel Two gel layers: stacking gel and resolving gel Relatively easy to set up Relatively more difficult to set up Ethidium bromide staining for DNA Coomassie or silver staining for proteins   Producing Reliable Results The key to successful gel electrophoresis is to optimize the operating parameters, including voltage, buffer selection, buffer pH, dye, appropriate reference marker, and more. Any of the aforementioned elements may have an impact on how clearly the gel electrophoresis result is resolved. A matrix's pore size is determined by the concentration of the polyacrylamide or agarose gel, which is crucial. A result can only be obtained if the sample size can pass through the pore size. For biological molecules whose charge does not change, voltage, in addition to pore size, controls the rate of migration. Thus, you may adjust the voltage and gel % to acquire the best electrophoresis results. It's also crucial to select a buffer that works for your experiment's design. Applications that will be made following the electrophoresis process are also a crucial factor to take into account when choosing the appropriate buffer. Regardless of whether you use a protein ladder or a nucleic acid reference marker, it is crucial to have even the tiniest indication of the expected product size. The assessment of product size will be challenging if a ladder that is beyond the product range is used. When separating mixtures including DNA, RNA, and protein molecules, gel electrophoresis is a common scientific technique utilized. Gel electrophoresis may be done in two different ways: vertical and horizontal. Whereas the running buffer is discontinuous in vertical gel electrophoresis, it is continuous in horizontal gel electrophoresis. Vertical and horizontal gel electrophoresis differs in this way. The common concept of gel electrophoresis underlies how both systems operate.
