Abstract:
Electrophoretic mobilities of progesterone particles dispersed in aqueous solutions of D-glucose and urea (concentration range 0.1 to 1 mM) have been measured in order to investigate the electrical properties of the interface. Zeta potentials have been determined for this purpose. The dependence of Zeta potentials on concentration has also been examined. Theory of the electrical double layer has been used to explain the results.

DNA Agarose Gel Electrophoresis
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...
