Morphology

isoelectric = electric (semi-transparent) = iso + electric

The structure iso- + electric is transparent, but the medical/technical extension ('no detectable electrical activity') is specialized and may not be inferable by general learners.

Etymology

Isoelectric comes from iso- meaning 'equal' and electric meaning 'electric signal', and a helpful way to remember the medical use is to think of a 'flat line' where the electricity is 'equal to zero' and no activity is seen.
