Quizplus · Accepted Answer

MPO (Myeloperoxidase) and SBB (Sudan Black B) are two stains commonly used to differentiate between myeloid and lymphoid blasts. MPO is present in granules of myeloid cells but absent in lymphoid cells, while SBB is absorbed by the lipids in lymphoid cells and stains the granules in myeloid cells. Therefore, these two stains are effective in identifying the lineage of blasts.
