What kinds of biological buffers are used in electrophoresis?
Latest company news about What kinds of biological buffers are used in electrophoresis?

Biological buffers are an important part of electrophoresis technology and are generally added to the solution to stabilize the pH when current is passed through the sample. In addition, the buffer can also provide the ions needed for electrophoretic migration.

 

The ideal buffer for electrophoresis depends on the isoelectric point of the sample being analyzed.

 

Although there are many pre-made buffers for electrophoresis on the market, it is recommended to use the biological buffers prepared by yourself to make your own solutions.
