2. Whether the target strip is clear, whether there is tailing or not, whether mark runs clearly and whether it can represent the size of the strip.
According to whether the supporting medium is used in electrophoresis, it can be divided into free electrophoresis and zone electrophoresis. Free electrophoresis does not use supporting medium, and electrophoresis is carried out in solution. This kind of electrophoresis is divided into two types: non-free interface electrophoresis and free interface electrophoresis. Non-free interface electrophoresis means that all charged particles (such as various cells) suspended in the solution move after being electrified, and there is no interface, such as micro-electrophoresis.
Extended data:
The resolving power of gel is related to the type and concentration of gel. The resolving power of agarose gel is 0.2~50kb, while that of polyacrylamide gel is higher, and it can resolve DNA fragments with smaller molecular weight, and its resolving power is 1~ 1000bp. The gel concentration affects the pore size of gel medium. The higher the concentration, the smaller the pore and the stronger its resolution. On the other hand, with the decrease of concentration, the pores will increase and its resolution will be weakened.
