electroendosmosis การใช้

Electroendosmosis is a reason agarose is used preferentially over agar as agaropeptin in agar contains a significant amount of negatively charged sulphate and carboxyl groups.
Electroendosmosis is a reason agarose is used in preference to agar as the agaropectin component in agar contains a significant amount of negatively charged sulphate and carboxyl groups.
These negatively charged groups create a flow of water in the opposite direction to the movement of DNA in a process called electroendosmosis ( EEO ), and can therefore retard the movement of DNA and cause blurring of bands.
