Cellulose Acetate Gel Electrophoresis

The composition and properties of the analyte often depend on various wonderful methods. Today there is a technique of cellulose acetate gel electrophoresis, which is quite delicate.

This technique uses cellulose acetate gel as a medium, with uniform quality and fine pores, which allows the sample to be shifted in an electric field according to its charge, amount, and molecular size and shape. When the sample is placed on the gel and an electric current is applied, the positively charged one will tend to the cathode, and the negatively charged one will tend to the anode.

When operating, first prepare the cellulose acetate gel to make it uniform in thickness and suitable in texture. Then properly spot the sample to be analyzed at the beginning of the gel. Turn on the power supply, regulate the voltage, current and time, so that the sample swims in the gel in an orderly manner. After time has passed, the sample strip can be revealed with a suitable dye solution, and its separation state can be observed.

This cellulose acetate gel electrophoresis method is widely used in biochemical, medical and other fields. It can analyze the components of proteins and help doctors diagnose diseases; it can distinguish the fragments of nucleic acids, which is the secret of genetics for researchers. The method is convenient, sensitive and high resolution, which is actually a powerful tool for analyzing the composition and characteristics of substances.
