Explain your question a little more, I will try to answer you :

- on SDS-PAGE (protein) of oral mucosa cells , typical voltage is 80–100 V for stacking and 120–200 V for resolving. The current is usually around 20–45 mA, depending on the gel size and system.

- on Agarose Gel Electrophoresis (DNA) of oral mucosa cells, you can use a voltage: 90–150 V and current: 50–100 mA depending buffer (TBE or TAE), the gel size.
