DIFFERENCE BETWEEN MORDANT AND ACCENUATOR IN STAINING
MORDANT and ACCENUATOR both are terms used in staining, for substances which enhance staining. However, both have different mechanisms of action. We will be looking at the difference between mordant and accenuator in staining. Differences between mordant and accenuator MORDANT MORDANT serves as a link or bridge between the tissue and the dye, to make […]

Periodic acid schiff (PAS) staining patterns in hematopoietic cells
Different hematopoetic cells stain differently with PAS stain. Let’s look at various PAS staining patterns in hematopoietic cells. 1. MYELOID PRECURSORS AND NEUTROPHILSMyeloid precursors show diffuse PAS positivityNeutrophils show intense granular positivity 2.MONOCYTES AND THEIR PRECURSORSMonocytes and their precursors show variable diffuse positivity. 3.ERYTHROID PRECURSORS AND RED BLOOD CELLS (RBCs)Red blood cells are PAS negativeErythroblasts […]
