2) a better option is that Bio-Rad provides concentrated marker solutions (low and high range) which has to be diluted with reduced sample buffer before loading. So instead of reduced you can add the non-reducing buffer and use this as the nr ladder.
you won't be able to trust the results if you don't run them as prescribed.
