Every time i am facing this type if problem. I used volt free and 22mA current for the separation of whole cell extract proteins.During the run,my current flow fluctuates.What is the reason behind this scenario?
Hi, I have had these humps in my gels. These could be a result of different environment inside and outside the cassette. For me- readjusting the pH of the running buffer and using a freshly made buffer resolved the issue. If reusing the buffer then checking the pH and mixing it uniformly before using for next cycle also help.
