When we talk about an ionic buffer for electrophoresis, pls note that the buffer for PCR and gel electrophoresis is different in that the former specifically contains Mg2+ because Mg2+ serves as a co-factor for Taq polymerase. If you go on to search online, I am sure you will be able to find other functions for the Mg2+ too tho I think the above-mentioned is its lead role.
