Gel electrophoresis can be conducted in either a horizontal or vertical orientation. Horizontal gels are typically composed of an agarose matrix. Pore sizes of these gels depend on the concentration of chemical components: agarose gel pores (100 to 500 nm diameter) are larger and less uniform compared to that of acrylamide gelpores (10 to 200 nm in diameter). Comparatively, DNA and RNA molecules are larger than a linear strand of protein, which are often denatured prior to, or during this process, making them easier to analyze. Thus, DNA and RNA molecules are more often run on agarose gels (horizontally).Our DYCP-31DN system is a horizontal electrophoresis system. This molded gel casting device can make 4 different sizes of gels by different gel trays.
