JC,

That might work. The WHO nomenclature is only likely to be useful for the scientists seeking and unambiguous naming system.

For the rest of us, just a brief explanation should suffice.

IMO, an mAb is just a medical or physiologic tool, like a laser.

Is it a laser used to measure distances and map spaces?

Is it a laser engraving my stethoscope so I don't have a third one stolen in three years?

Is it a laser heating and destroying an enemy drone to protect our servicemen and women?

Same underlying technology but wildly different applications.
